establish a small commissariat dépôt, in order that troops may break their march there. As we rode down this dry parched valley for thirty miles, occasionally meeting detachments of weary men, who asked us pitifully how far it was to water, we could not help thinking of one of Colonel Phayre’s reports, in which he stated, “From Sooro to Senafe, about thirty miles more, water never fails.” The fact being, not one single drop is to be found in the thirty miles above Sooro, save at one muddy well. At Koomaylo I found an astonishing change. The thorn-trees which had lined the bottom of the valley had been all cut down; a large space had been cleared as a camping-ground for troops as they march through; fresh wells have been sunk, and there are some of the American pumps at work, discharging a stream of clear water, which, flowing through a succession of tubs, enables the animals to be watered in one quarter the time formerly occupied. These pumps, which are called “the Douglas pitcher-spout pump,” are certainly admirable machines. When I had first heard of their arrival, and of the principle of their construction, I had not thought it possible that they could be used in such ground as this. They consist of a number of thin iron tubes like gas-pipes, screwing into each other, the lowest one terminating in a sharp spike of slightly bulbous form, so that, being thicker than the rod itself, it only touches the soil through which it is driven at that point, thus greatly diminishing the friction and resistance. On to the pipe, at about four feet from its upper end, is screwed a block of iron, which can be shifted as the rod gradually descends. A heavy weight of iron, with a hole through it, is put on the rod above this block, and to this weight ropes are attached working through pulleys placed on the top of the rod four feet higher. Two men pull these ropes, and the weight rises, and then falls, acting as a rammer upon the anvil of iron below. In this manner the whole rod is driven down, fresh lengths being added as required, and then a pump is established without the labour of sinking a well. The whole thing is simple in the extreme, and admirably adapted for clay or gravel soils. It could, however, hardly be expected to be successful in the bed of a torrent, where the gravel is mixed with blocks of stone of every size, as it is evident that a hollow pipe could not be driven through solid rock. The tube, however, in nine cases out of ten, pushes any obstacle aside, and reaches the required depth. It is intended to arrange a series of troughs, so that the animals may be enabled to drink upon their arrival without the weary hour of waiting which they have now to go through. Indeed, it is a wonder that serious accidents have not occurred owing to the eagerness with which the maddened animals struggle and fight to get to the water. At Koomaylo we found two companies of the 33d regiment. They
