The other men were laughing all the time, saying that they felt no pain at all; but their boast did not last long, for a few moments later, while I was watching poor Filippe, Antonio and the man X threw themselves down on the rocks, rolling over and contorting themselves, evidently in most excruciating pain.

The same treatment was applied to them in turn, and I watched with great concern three men out of the six spread out helpless, and in such a dreadful condition that I really doubted whether they would be alive in another hour. I considered myself fortunate that the other three had not been poisoned.

Half an hour later—it was impossible to move on with the three men lying helpless on the rocks—Filippe the white man and Benedicto also collapsed. Again the same treatment once more.

Alcides looked at the other men with an air of contempt and said: "They are rotten fellows! They cannot eat anything without getting poisoned. I feel no pain at all; the fruit has done me no harm."

When I turned round to look at his face it had turned a lemon-yellow colour, which I did not quite like, but I did not mention the fact to him, and went about from one dejected man to another to try and bring them back to life again.

Filippe the negro opened his eyes for a moment. "I am dying!" he said. "Good-bye, sir! Please give all my money to my sweetheart in Araguary."

I noted her name and address in my book, for I really thought Filippe was about to expire.

The moans and groans all round me were most funereal, and the odour unbearable, the nuts having formed a chemical combination in their insides which made their breath most offensive. The heat in the sun was oppressive on those volcanic rocks. My bare feet were absolutely scorched as I walked on them.

Not many minutes later Alcides was rolling himself upon the rocks in intense pain. When I rushed to him to apply my favourite method he rebelled, refusing the treatment.

"Very good," I said to him; "will you live or will you die?"
