I had from the first been convinced that the smallest number possible would also be, in our case, the wisest. The immense extent of the country to be traversed, and the difficulties which must inevitably lie in our way to hinder and delay us, as well as the practical emptiness of the country, which requires that an expedition shall be self-supporting, were salient facts; and our plans had to be made and modified in relation to these facts. The mobility of the party was the main point to aim at. Hence it was necessary to cut down the _personnel_ of the expedition to as low a number as possible, and it was further most important to have plenty of horses and to spare.
The difficulty of feeding several men when travelling through such a country was obvious, and therefore not to be thought of, as, besides the four horses each individual needed for riding, the extra animals for carrying provision and bedding, clothing, tents, &c. had to be taken into account. No pack-horse should be allowed to carry his load two days consecutively, and, in fact, one day's work in three is enough. If waggons are taken, each should be allowed three teams of six horses each.
With such ideas in view, those arrangements were made which, in fact, enabled us to cover the distances we achieved. Any expedition of this sort is killing work for the horses, and it stands greatly to Burbury's credit that we lost but one out of nearly sixty during the months we spent in Patagonia, and that one was a colt that died of eating poison-shrub.
There is not the slightest doubt that the policy that spells success in Patagonian travel is summed up in the words, "Cut down your men and your stores, and take enough horses to enable you to move lightly and rapidly."
On September 21 we left Trelew in the afternoon. The weather was magnificent. Our caravan at this period consisted of a couple of waggons as well as the horses. Two _estancieros_, Messrs. Greenshields and Haddock, accompanied us, as our way led past their farms. I sent the waggons ahead and rode on afterwards with Burbury and Humphrey Jones senior. When we came to the place fixed on for our first camp we found the men had gone on, for there was no water there. We pushed forward in the dark, and presently the fire of the encampment glimmered out in front of us; it seemed to be quite near, but it took a good while to reach. We heard an occasional fox, and as we sat round the fire a few birds passed in the dark, calling. The first night in camp is like the first night at sea, a gloomy time.
