"It's of no use putting it back," said the other ; "parr or not, it's dead.” “It may dee and be dom'd; I wash my hands of it,” was the reply with which my profane friend placed me in the water, carefully enough. I felt sick and helpless; without power to sustain my proper position, I floated, with my back downwards, until I rested against some long floating grass, a few yards from the boat, to which the eddy of the stream had carried me. Although too weak to move, I retained my senses, and heard the younger man say to his companion—"Why, John, what made you throw that poor little dead beast into the water again?” “Deed," was the reply, “yon beastie's just a smolt, an' there's a fine for killing sich like.” “But you killed a parr just now ?” “Ay.” “But you call this a parr?”

pleasing part of the process is to watch them in the infected grain from the first entrance till their maturity. To do this, it is requisite to have the wheat growing close at hand, so that daily access to it can be had, and the time I recommend for commencement is as soon as the grain begins forming in the ear. The first object to be sought is the parent eel filled with eggs. These, when first extruded, are of a dark colour, and opaque, but gradually become more transparent, at which time the young eels will be seen curled up in various figures, and slowly moving round in their shells, from which they ultimately break forth and con. tinue to live on the farinaceous matter of the grain till all is consumed, when they become torpid, and so remain till brought again to life by means similar to those which gave activity and instinct to their parents.

But the difference is very marked when carefully examined with a high magnifier.-4. Nicholson.
