On the trail one speedily learns the significance of the phrase “Indian file.” Here are none of the advance guards, flank guards, and rear guards that are needed to penetrate unfriendly country in other lands. The first man hacks a way for those who follow, and the bush is left as a wall on either side that is as inscrutable to the possible enemy on the flank as to the advancing party. On account of such conditions I should say, from my experience of bush travel in these regions, that the whole party should rarely if ever exceed twenty-five in number. On this principle it will be seen that the smaller the quantity of baggage carried the greater will be the number of rifles available for the security of the expedition.

The difficulty of an efficient food supply is very great. Game is always hard to shoot on account of the density of the bush, and in many parts appears to be non-existent. Preserved goods in sealed cases, of convenient size for porterage, should be taken from Europe. My failure to carry out my original intentions was due more than anything else to the fact that my supplies were purchased in the country, and 50 per cent proved unfit for consumption. The country where supplies must be husbanded has little enough of food that is appetising to offer. Fish, if plentiful, are hard to catch for the uninitiated. One hungers for the occasional tapir or peccary, the joys of monkey-meat, and an incautious, though unpalatable, parrot, and in the days of real distress may be glad to fall back on frogs, snakes, and palm-heart. The real fear of starvation, after perhaps the ghastly dread of being lost, is the great cause of anxiety to the traveller in the Amazons.

As for shelter,—a tent is an encumbrance,—an open screen of rough palm thatch can be erected in a very short time, and is all that is necessary, although not all that is to be desired. The shelter is a poor one that does not prevent the dews and the inevitable rain from chilling one to the bone.

Clothes for the Amazons are not designed with a view to fashion or appearance. In the past, continental explorers have introduced some interesting fashions in ducks and khaki, but travelling through a country where one’s life is passed in a bath of perspiration, their distinction of appearance yields to the simple comfort of the native’s nudity. In search of a compromise, I have found that a thin flannel suit of pyjamas with the trouser-legs tucked into the socks, and a pair of carpet slippers laced over the instep, best meet the requirements of the region. Ordinary boots are a positive danger on account of the narrow and sometimes slippery tree-trunks over which one clambers uneasily. A small towel round the neck to wipe away the perspiration is a great comfort. For head-gear a cloth cap or “smasher” hat suffices.

A long knife or cutlass must be carried, and, personally, I invariably carried a revolver, while the gun-bearer should always be at hand with a rifle or scatter-gun. A blanket, sleeping-bag, and waterproof sheet of course must be taken, with the other comforts, medical and hygienic, common to all expeditions.

The drawings that appear in this volume are either taken from photographs or from actual trophies and articles in my possession. The photographs are a record of industry and patience. Films I found useless in this climate, and plates alone materialised. It must be remembered, also, that every time plates have to be changed it is necessary to build a small house, and double thatch and treble thatch to prevent the entrance of any light. Even then the experienced do their work at night.

The difficulty of posing and overcoming the objection of the native subject will be at once realised. Too many groups have been draped by explorers in the unaccustomed decencies of camp equipment, though it has become an essential of the country—climatic and psychological—that the women walk abroad naked and the men unembarrassed by more than a loin-cloth.

The maps cannot pretend to be more than the roughest approximate sketch-maps. When absence of a horizon and the density of the bush are realised, it will be obvious that they can be nothing more. It is hoped that they will suffice to give some idea of the general trend of the country and the location of the various language-groups.
