dirty cotton rags. This was the limit of my journeys in this direction, although the path continued on to the savannahs towards San Thomas. The soil at this place is good, and I think that it has been long cultivated, as much of the forest appears of second growth, in which small palms and prickly shrubs abound.

On the northern side of the Santo Domingo valley, opposite to my house, a branch valley came down from the north, which we called the San Antonio Valley. It intersected all the lodes we were working, and I constructed a tramway up it as far as the most northern mine,called San Benito, by which we brought down the ore to the stamps and the firewood for the steam-engine, and in a short time we had cleared all the timber from the lower part of the valley; and a dense scrub or second growth sprang up, through which numerous paths were made by the woodcutters. I was almost daily up this valley, visiting the mines, or in the evening after the workmen had left, and on Saturdays afternoons, when they discontinued work at two o'clock. On Sundays, too, it was our favourite walk, for the tramway was dry to walk on; there were tunnels, mines, and sheds at various parts to get into if one of the sudden heavy showers of rain came on; and there were always flowers or insects, or birds to claim one's attention. I planned the whole of the tramway; the upper

half I surveyed and levelled myself; and my almost daily walks up it familiarised me with every bush and fallen log by its side, and with every turn of the clear cool brook that came prattling down over the stones, soon at the machinery to lose its early purity, and be soiled in the ceaseless search for gold.
The sides of the valley rose steeply, and a fair view was obtained from the tramway in the centre over the shrubs and small trees on each side, so that the walk was not so hemmed in with foliage as is usual in the forest roads. Insects were plentiful by this path. In some parts brown tiger beetles ran or flew with great swiftness; in others, leaf-cutting ants in endless trains carried aloft their burdens of foliage, looking, as they marched along with the segments of leaves, held up vertically, like green butterflies, or a mimic representation of a moving Birnam wood. Sometimes the chirping of the ant-thrushes drew attention to where a great body of army-ants were foraging amongst the fallen branches, sending the spiders, cockroaches, and grasshoppers fleeing for their lives, only to fall victims to the surrounding birds. On the fallen branches and logs I obtained many longicorn beetles ; the woodcutters brought me many more, and from this valley were obtained some of the rarest and finest species in my collection. On the myrtle-like flowers of some of the shrubs, large green cockchafers were to be found during the dry season, and a bright green rosechafer was also common. I was surprised to find on two occasions a green and brown bug (Pentatoma punicea) sucking the juices from dead specimens of this species. The bug has weak limbs, and the beetle is more than twice its size and weight, and is very active, quickly taking wing; so that the only way in which it could be overcome that I can think of, is by the bug creeping up when it is sleeping, quietly introducing the point of its sharp proboscis between the rings of its body, and injecting some stupefying poison. In both instances that I witnessed, the bug was on a leaf up a shrub, with the bulky beetle hanging over suspended on its proboscis. Other species of bugs certainly inject poisonous fluids. One black and red species in the forest, if taken in the hand, would thrust its sharp proboscis into the skin, and produce a pain worse than the sting of a wasp. Amongst the bushes were always to be found the beautiful scarlet and black tanager (Rhamphocoelus passerinii, Bp.), and more rarely another species (R. sanguinolentus, Less.). Along with these, a brownish-coloured bird, reddish on the breast and top of the head (Phænicothraupis fusicauda, Cab.), flew sociably; whilst generally somewhere in the vicinity, as evening drew on, a brown hawk might be seen up some of the low trees, watching the thoughtless chirping birds, and ready to pounce down when opportunity offered. Higher up the valley more trees were left standing, and amongst these small flocks of other birds might often be found, one green with red head (Calliste laviniæ, Cass.); another, shining green, with black head (Chlorophanes guatemalensis); and a third, beautiful black, blue, and yellow, with yellow head (Calliste larvata, Du Bus.). These and many others were certain to be found where the climbing Marcgravia nepenthoides expanded its curious flowers. The flowers of this lofty climber are disposed in a circle, hanging downwards, like an inverted candelabrum. From the centre of the circle of flowers is suspended a number

This liquid attracts insects, and the insects numerous insectivorous birds, including the species I have mentioned and many kinds of humming-birds. The flowers are so disposed, with the stamens hanging downwards, that the birds, to get at the pitchers, must brush against them, and thus convey the pollen from one plant to

another. A second species of Marcgravia that I found in the woods around Santo Domingo has the pitchers placed close to the pedicels of the flowers, so that the birds must approach them from above; and in this species the flowers are turned upwards, and the pollen is brushed off by the breasts of the birds. In temperate latitudes we find many flowers fertilised by insects, attracted by honey-bearing nectaries; and in tropical
