It is probably in recognition of his contributions to chemical science, more especially, that our northern friends delight to honour their departed townsman. We are not aware that in his capacity of Master of the Mint Mr. Graham did very much to warrant his being singled out for commemoration in bronze and granite in the centre of a great city.

We have here sketched the general appearance of the aurora borealis, but there have been aurora which have presented striking peculiarities. These consist in appearances as of a curtain of wavy light hanging from a mass of clouds above. Of such a nature was an aurora observed at Bossekop in Lapland in 1838, the curtain of light with its wavy undulating folds being beautifully brought into full relief. Sometimes this curtain seemed to consist of separate ribbons of light arranged side by side in groups of different lengths, the lower edges being fringed with brilliant rays. The whole formed an object of exceeding beauty, which finally faded away, as all things, even the most beautiful, must in time.

TRIAL OF THE "KIRKSTALL" STEAM
SHIP.

VERY successful trial of the steam ship "Kirkstall" took place on Wednesday last over the measured mile off Shoeburyness The ship has been built by Messrs. Allibon and Noyes, of Northfleet, Kent, for Messrs. Dawson and Co., of Goole, and is to be employed for transporting barrelled beer between their breweries and the London stores. Through the kindness of Messrs. Allibon and Co. we were allowed to accompany the boat on that occasion for the purpose of witnessing the working of the engines which have been placed in her. These engines are of novel construction, and such as, we venture to say, have never been seen before in a vessel. They consist of two sets of cylinders, one set (the smaller, being above the other or larger set, and when the steam has done its work in the smaller one it is exhausted into a reservoir, from which it is taken for use in the larger cylinders. By this means the whole of the force contained in the body of steam drawn from the boilers is utilised. The small cylinders are connected piston rods of the

Continuing our record in order of occurrence, we next come to a brilliant display of the aurora which took place on Monday evening last. As seen through the murky atmosphere of London, it appeared to cover the heavens with crimson. Accounts from the provinces, however, speak of its principal hue as a brilliant carmine in a band of great width, stretching from east to west, with vivid corruscations of white and yellow flashing incessantly from its northern and southern sides. The display as observed by a resident in the higher parts of the north-western suburbs of London, and described by him, was very grand. He says the sky was very luminous at sunset, and, shortly after, indications of the aurora were apparent. About 6.30 a broad streak of red light covered It is a very rare thing for the aurora to be the stars Alpha and Beta Arietis, and continued manifested in this country with the distinctness for a considerable time.

After passing the paper through rollers several times, the upper surface acquires the appearance of leather; it is then coloured, oiled with a kind of rape-seed oil, varnished, put once more in the press, which completes it, with the exception of drying. By means of parallel or cross lines on the rollers the upper surface of the paper is made to resemble leather exactly in all its varieties. The paper being pressed to one-third or even one-half its original thickness, and the passage through the rollers giving ft a fine grained appearance, makes it valuable to picture printers, as the surface has the appearance of crepe silk.

There is another variety of leather paper which is smooth and transparent, resembling hog skin very much. This is manufactured by a process of hammering, and is the highest priced, costing 27 cents per sheet, while the other ranges from 8 to 14 cents, some very fine selling at 8 cents per sheet.-"Ex." in "Technologist."

IMPROVEMENTS IN HULLING GRAIN.

MESSRS BROWN and POLSON, the celebrated cornflour factors, of Paisley, have just patented some improvements in apparatus for hulling grain, which they carry out in the following manner. Under one arrangement the mechanism by which the hulling or husking of the grain is effected consists of a cylindrical or conical barrel or drum placed either horizontally or inclined, which is revolved at the requisite velocity and situated inside a cylindrical or conical casing, the barrel or drum and casing being of such dimensions that a space is left between them. The barrel or drum is wholly or partly covered with a sheet or sheets or strips of perforated iron or steel, whilst the cylindrical casing is also composed of similar perforated iron or steel. At one end of the casing a passage or duct is provided through which the grain to be hulled or husked is admitted, and at the opposite end of the casing another duct is provided, through which the grain after being hulled or husked is discharged. For the purpose of cooling the working parts of the hulling or husking mechanism as well as the grain itself the duct by which the grain is admitted is provided with an air chamber and fan or exhauster by which cold air is drawn through perforations in the ends as well as in the duct to the mechanism, thereby keeping it as well as the grain at a sufficiently low tempe

rature.

[blocks in formation]

Fig. 1 is a longitudinal section, fig. 2 is a transverse section, and fig. 3 is an end elevation showing one modification of apparatus for hulling or husking grain. The mechanism consists of a cylindrical barrel or drum A, constructed of segments or staves of timber B, and attached at both ends to discs C C, fixed upon the revolving shaft or spindle D. The external cylindrical surface of the barrel or drum A is covered by perforated plates or strips a of steel or iron. Upon one end of the shaft or spindle D a driving pulley E is fixed for communicating a rotary motion to the barrel or drum, which is situated within a perforated cylindrical casing F, fixed at both ends to rings G G carried by the arms and boss V and free to revolve upon the shaft or spindle D. At the centre thereof, and upon the exterior of the casing F, a ring H having spur teeth is fixed, which gears into a pinion I fixed upon a shaft J carried in bearings in the end frames K K.

Upon one end of the shaft J is a pulley L for communicating a rotary motion to the shaft J by means of a strap or belt b driven by a small pulley M fixed upon the corresponding end of the shaft or spindle D, and through the medium of the spur wheel H and the pinion I a rotary motion is conveyed to the casing E at a velocity equal by preference to 1-25th or thereabouts of that of the barrel or drum A, which may be in a direction contrary to that in which the barrel A revolves or in the same direction. The exterior casing of the apparatus consists of end frames K K bolted at the lower part to side frame plates N N. whilst the top or covering, which is semicircular, is of sheet iron extending between the end frames K K, and secured to flanges c c, by means of rivets or bolts. Upon one of the end frames K, a passage O is formed in the manner shown, to which a pipe P is attached, having by preference through a portion of its length an outer shell or casing Q, the position of which, as shown in the drawings, forms an annular space R around the passage P, and to the lower part of which a small drip pipe d is attached, provided for the purpose of withdrawing any superfluous water that may collect in the space R through the condensation of the steam contained therein. In place of steam water may be admitted into the space R. The air-tight chamber S wherein the working parts of the apparatus are situated terminates at

the lower side in a duct T formed as shown, and leading to a fan or exhauster.

The grain which is to be husked or hulled is admitted through the passage P, and into the annular space R steam or water is admitted; the said pipe P is perforated as shown for the purpose of allowing the steam or water to moisten the grain during its passage through the passage P. In travelling downwards through the duct Ŏ the moistened grain falls into the space between the revolving casing F and drum A, which may revolve in opposite directions, as indicated by the arrows upon fig. 2, and at different velocities as before mentioned.

The grain is thus exposed to a rubbing or triturating action between the perforated plates a upon the barrel or drum A and those forming the casing F, whereby the outer coating or husk is removed from the inner portion of the grain. This rubbing process is maintained throughout the entire length of the barrel or drum A as the grain travels along its surface, and when having arrived at the end opposite to that into which it was admitted the grain then drops into and is discharged through a duct U formed in one of the end frames K. During the whole of the operation now last described a current of

cool air is drawn through the perforations e, both in the duct O as well as in the ends K, passing through the grain and over the working parts of the apparatus, thereby keeping the grain as well as the mechanism at a low temperature whilst the hulling or husking operation is continued. The said current of air is occasioned and drawn downward by means of an ordinary fan or exhauster conveniently placed at the outer end of the duct T.

OPERATING THE DAMPERS OF STEAM BOILERS.

HE apparatus illustrated above is for working or operating dampers or regulators for governing the draught or passage of air or waste currents from furnaces, and is applicable not only to the flues of steam boiler furnaces, but also to the flues of other furnaces where the pressure due to the expansion of either elastic or liquid fluids or gases can be obtained and made available for actuating the apparatus.

The invention will be understood by referring to the engravings, a patent having been obtained for it by Mr. F. Brusch, of Kingston-upon-Hull, where fig. 1 is an elevation of the working parts of the apparatus, fig. 2 being a plan of fig 1; fig. 3 is a vertical sectional view of the apparatus, taken on the line A B. In each view the diaphragm, which is there shown as a plain surface or sheet of elastic material, and the loosely fitting piston and other moving parts of the apparatus, are shown as being at rest, or without any pressure acting thereupon.

IMPROVED MEANS OF PROPELLING

VESSELS.

AMONG the patents recently granted in this country is one for an invention for propelling vessels by means of revolving blades fixed upon arms which are keyed to bosses, one of which runs loosely upon the longitudinal shaft projecting

speed than when both sets revolve in the same direction.

Mr. Tyrer, of Birkdale, Lancashire, the inventor, however, proposes that in some cases the two sets shall revolve the same way.

TRIAL TRIP OF THE "ABYSSINIA.” HE "Times" of November 2 gives the following: The Abyssinia, breast work monitor, 1,849 tons, 200-horse power of engines, carrying two double-gun turrets, and driven by twin screws, built for the defence of Bombay, to order of the Secretary of State for India, by Messrs. J. and W. Dudgeon, of Millwall, under Admiralty supervision, was put through her final trial of machinery and speed yesterday over the measured mile off the Maplin Sands, previous to her sailing for Bombay, the trial being conducted by Government officers, and in accordance with the rules observed on the trials of all of her Majesty's ships. The "Abyssinia" left Gravesend on Monday, and after steaming as far as the Maplin Sands, went into Sheerness harbour and anchored there for the night. Yesterday morning she left the harbour again for the trial ground. The Admiralty officials on board comprised:-Mr. Barnes, member of the Admiralty Council of Construction; Mr. James Steil, Admiralty Inspector of Machinery; StaffCaptain Kiddle, of the Sheerness Steam Reserve; Mr. W. Steil, Assistant-Master Shipwright and Engineer, Sheerness Dockyard; Mr. T. T. Murray, Inspector of Machinery, Sheerness Dockyard; and Mr. Laslett, Admiralty Surveyor.

The ship's draught of water was 13ft. 7in. forward and 14ft. 8in. aft, giving a mean draught of 14ft. 1 in. At her load line the ship will float at 15ft. forward and aft., with the main deck having a freeboard of 3ft. A strong wind prevailed off the Sands during the time the ship was being tried, and a lumpy sea was running, but the results were considered very satisfactory by all the officials on board, the ship under full boiler power, without being pressed in any way, or the power of her engines brought out to their full extent, averaging as a mean of six runs made over the measured mile, 9.600 knots per hour. Under half boiler power she realised a mean speed of 7.827 knots. The mean revolutions of the engines at full boiler power were 117.5 per minute. In trying the ship over circles after the speed trials had been con

olded, and the circle was made to port in 2min. 12sec., and the full circle in 4min. 52sec. To starboard the half circle was made in 2min. 10sec., and the full circle in 4min. 42sec. The angle the rudder was put over in each instance was 30deg. In testing the action of the engines, in reversing their motion to signal from the hurricane deck, the results obtained were equally satisfactory with others, connected with their power and speed, each pair to port and starboard stopping dead in 15sec., starting astern to full speed from rest in 5sec. and 6sec. respectively, and changing from full speed astern to full speed ahead in 4sec. and in 6sec. respectively. The engines were structed by the builders of the ship, and consist of two pairs of inclined cylinders, direct-acting, the diameter of the cylinders being 34in., and the spoke of the pistons 21in. They drive two threebladed screws, each of 9ft. 6in. diameter. The distance between the centres of the screw shafting is 13ft. 6in.

The "Abyssinia" is one of three vessels of the low freeboard Monitor type that have been built for the defence of our colonial harbours, the

Magdala" being the second vessel, also for the defence of Bombay, and the "Cerberus," which sailed from the Nore on Saturday for Plymouth and Melbourne, being the third. The two latter exceed the "Abyssinia" in tonnage and engine power, but all three are exactly alike in design and arrangement of their decks and turrets as low freeboard Monitors, carrying their turrets inside an armour-plated breast work, or smaller deck built upon the main deck, and covered-in low-swimming hull of the ship. In one very important respect, however, there is at present a very great difference between the "Abyssinia and her consorts. The former floats purely and simply as a Monitor without rig of any kind aloft, and with only two light pole stars for signal staffs. The "Cerberus" and the "Magdala" are both bark-rigged for their voyage out, and with the certainty that sail power can under no circumstances be of any service to them, and very probably will be found to seriously imperil their safety. The "Cerberus " may or may not carry her spars and sails with her from Plymouth to Melbourne at all risks, but it is believed to be the wish of the Controller of the Navy to take the "Magdala's" masts out of her again and send her out to Bombay under steam alone, as the "Abyssinia " will go out via the Suez Canal. In appearance nothing can well be imagined more unsightly than the three Monitors, more especially the two hampered with the absurdity of masts and sails; but

II. RECRUITING.

The name of every male citizen of Prussia is since 1809 entered upon the army lists actually at his birth. The civil authority, upon receiving the usual notice of the birth of a child, reports the names of the males to the commander of the "Landwehr Battalion." He represents the territorial military authority; and his district is coextensive with one or sometimes two "circles," as they call what we call "counties." Every Prussian is bound by law, as long as he is not yet excused from all military duty, or as long as he has sons under the age of twenty, to report any change of residence, that is to say, any change of his home for good.

Emigrants have been very numerous from Germany, simply because the soil is no longer adequate to the wants of the steadily increasing population; but this movement excepted, the German is steady and not given to moving aboutthe less so, as to give up what he has got before he has got something better is very dangerous in a country where labour is in excess of the demand, and no uncultivated soil is to be found.. For this reason a regulation can be easily enforced which it would be impossible to carry out in the United States.

The French revolutionists, when attacked by the standing armies of their neighbours, revived the old principle of a national defence to its fullest extent. Enthusiasm made up for want of brains, especially as the opposing armies were commanded by superannuated martinets, bewildered by the new spectacle. Tactics were adapted to the raw but abundant material, and finally Napoleon organised those French armies which in their victorious campaigns conquered nearly all Europe. Prussia, where the reminiscence of the glory of Frederick the Great had imbued the army and its leaders with a vanity sufficient in itself to preclude success, was in 1806 ignominiously overthrown by Napoleon.

a part of the 42,000 were dismissed on furlough,

Prussia was enabled in 1813 to increase at once

men up to the age of 35 years, furnished addi-
tional troops.

looking men, are taken for the corps of the guards; the tallest and strongest men are next designated built go to the hussars; tradesmen and mechanics are properly distributed; and the whole thing, descriptive lists included, is settled and reported. Formerly, when not yet every man was actually taken, lots were drawn immediately after the medical examination; and I cannot help remarking upon a great mistake in the draft law adopted during our great war, when we drafted before the examination had taken place, instead of examining first and drafting afterwards. Prussia is divided into military districts (Landwehr battalion districts) in such a manner that each district contains so many inhabitants that on an average about 200 each year reach the age of twenty. Of these 200 about 150 go to the infantry, 50 to all other arms of the service, cavalry, artillery, engineers, and administrative branches. The corresponding battalion of the line is 400 strong in peace time, one-third each year being dismissed to the reserve and replaced by recruits. The men remain in reserve six years up to their 29th year, and belong to the Landwehr proper during six more years. This gives a total number of 1,200 available for the line or field battalion, and 800 for the Landwehr battalion. The infantry recruits, after their three years' service, and those who have served somewhere else, all return home and remain under the orders of the Landwehr battalion commander. We propose to show by and by how all these soldiers are disposed of in case of a mobilization. Any of them changing their home report the fact, and their military record is transferred to such district as they choose to go to."New York Army and Navy Journal."

PARIS AND ITS DEFENCES.

the minds of Englishmen is, "what is to be done with Paris?" that city of which we are so proud, and in which we like to linger when we once set our foot in it. The subject of her defences has occupied an unusual degree of attention and interest for some little time past, that we are induced to give a view of the city with the fortifications around it.

Paris is situated, to use a military term, a cheval on the Seine, near this junction of this river with the Marne, the latter river covering the city on the east, while a bend of the former protects the western side. The fortifications consist, first, of a chain of detached forts or fortresses commanding the rivers, and, secondly, by an enciente continue running right round the city. The bastion system of Vauban is adopted throughout.

The exterior line of defence commences at St. Denis on the north, and extends to the Marne at Nogent, a distance of about eight miles. It consists of nine fortresses, and opposes the direct advance of troops from Germany. On the south Paris is covered by a line of six forts, reaching from the Marne to the Seine, a distance of about seven miles. These complete the defence of the south; four are pentagonal, and two quadrilateral. They are built of substantial materials, and contain bomb-proof barracks, and have casemated curtains. The third exterior line of defence is eight miles long. It does not consist of a chain of forts, but of the great citadel, Mont Valérien, which serves as a tete du pont to the bend of the Seine, which covers Paris to the east. Mont Valérien is supported on one side by Fort d'Issy, and on the

other by St. Denis. It is the most important work of the whole. The front towards the river is 460 yards each. There is a bomb-proof accommodation for stores and 4,500 men. The ring of detached forts, all of which will be easily found in our map, extends over 22 miles.

Within this is seen the enciente continue, or continuous line of fortifications. This consists of no fewer than ninety-four bastions. The exterior sides average 328 yards per bastion, forming an enciente of 30,840 yards, or nearly seventeen miles, probably the largest work of the kind ever executed. The cost was enormous-to judge from Marshal Marmont's opinion, was well spent. Marmont considered the fortifications of Paris "an event the most useful and important in the defence of France." The escarp of the enciente is 33ft. high, the ditch being 82ft. wide. The distance from the boulevard to the enciente continue averages about 1,093 yards, and that from the enciente to the forts is about the same. So long as the forts are unconquered it will be impossible to bombard Paris from a less distance than about 7,000 yards, and even then the siege train will be under fire at a range rather too close to be pleasant.

In addition to these defences it is stated that earthworks are being raised from fort to fort, but we learn from private letters that these are of a very insignificant description, affording good cover, it is true, for riflemen, but not safe against even 6-pounder guns. It is stated that more than 1,000 guns can be placed in position, but this estimate, no doubt, includes a very large number of weapons which, however effective at close quarters, will be practically useless at long ranges.
