August 31st was a painful day for me. Two of the men were badly laid up with fever, the others were most obnoxious. I had endless trouble in making them take up their loads and start once more. The man X said he would take the load which contained my instruments, but he would certainly leave it, as soon as he had an opportunity, concealed in a spot where it could not be found again. I told him in plain words that if he carried out his intention I would shoot him dead, and I would from that moment do the same to any other man who rebelled. I was surprised to find that the lot of them took their loads upon their shoulders and proceeded to march along as quietly as possible.

The Brazilian forest was—unlike the equatorial forest of Africa—comparatively clean underneath, there being very little undergrowth. It was quite easy to cut one's way through if one knew how. There was a great art in cutting one's way through the forest. If you happened to know the way trees grew or liane were suspended, it was easy enough to cut them with one sharp blow of the large knives. But if you did not happen to know the formation of the trees and you struck them the wrong way, you had to hit them many times before you knocked them down. The same thing and worse happened with liane, which could be severed easily with one stroke if it were applied the right way, but which wound round and entangled you in a merciless manner if hit at a wrong angle.

No observant person, however, experiences trouble in marching through the Brazilian forest, and if not hindered by impossible followers it would be quite easy to march long distances daily in any part of the forest without much inconvenience.

This statement only applies to the actual marching, and does not at all mean that you had not to go through severe sufferings and endless trials of other kinds. Unless you were careful where you were sitting, you found yourself spiked by thorns of great length which were strewn all over the forest hidden under the thick carpet of discarded foliage from the trees. Not only that, but the moment you sat down your body was simply invaded by swarms of ants of all sizes and degrees of viciousness, which proceeded to bite you all over with considerable vigour. There were not many mosquitoes where the forest was dense, but there were millions—in fact, milliards—of bees, which rendered your life absolutely unbearable, as they clung to your face, hands and clothes. Fortunately, they did not sting, but clinging with their claws upon your skin they produced such an irritation that you were nearly driven mad by it.

Then there were fetid bugs of huge size, the sickening odour of which when they touched you had quite a nauseating effect. They seemed to have a particular fondness for settling upon your lips or entering your mouth. When by mishap you swallowed them, their taste was something too appalling. Once or twice while I was eating I had the misfortune to crack one or two under my teeth. I had the bad taste of them in my mouth for hours after.

When we halted for lunch my men were in a shocking condition. I could not quite understand what had happened. Most of them seemed to suffer from violent internal inflammation accompanied by high fever.

In order to make things as easy as possible for them I once more rearranged the loads that afternoon, abandoning six hundred rifle cartridges, several tins of hyposulphite of soda, other chemicals, all the developing trays, etc., for my photographic work, and a number of valuable trinkets I had collected. Much to my sorrow I had also to abandon the geological collection, which was too heavy to be carried any farther. Then I had to abandon all the books which were necessary for working out my astronomical observations, such as Norrie's Navigation and The Nautical Almanac, and all possible articles which were not absolutely necessary.

After I had gone to the great trouble of unpacking everything in order to make the loads lighter, I was surprised to discover, a few minutes later, that the men had appropriated most of the stuff and shoved it back in their loads—in order, perhaps, to sell it when they got to Manaos.

I said nothing, as it suited me very well. I should have gladly repurchased the things from them on the way. One man opened a tin of powdered hyposulphite and, believing it to be powdered sugar, proceeded to pour it down his throat. Had I the bad habit of making puns, I should say that I just saved him in time from being "fixed" for good. As it was he swallowed some, and became very ill indeed for some hours.

We luckily killed a big mutum and two monkeys before leaving that camp, but my men were so ill that they left them on the ground, saying they had not the strength to carry them so that we might eat them for dinner. Well knowing what was in store for us, I proceeded to carry the huge bird (much larger than a big turkey) and one of the monkeys (as big as a child three years old) upon my shoulders.
