He became aware of Gerilleau beside him. "Capo," he said, "have you your glasses? Can you focus as closely as those planks there?"

Gerilleau made an effort, grunted, and handed him the glasses.

There followed a moment of scrutiny. "It's ants," said the Englishman, and handed the focused field-glass back to Gerilleau.

His impression of them was of a crowd of large black ants, very like ordinary ants except for their size, and for the fact that some of the larger of them bore a sort of clothing of grey. But at the time his inspection was too brief for particulars. The head of Lieutenant da Cunha appeared over the side of the cuberta, and a brief colloquy ensued.

"You must go aboard," said Gerilleau.

The lieutenant objected that the boat was full of ants.

"You have your boots," said Gerilleau.

The lieutenant changed the subject. "How did these men die?" he asked.

Captain Gerilleau embarked upon speculations that Holroyd could not follow, and the two men disputed with a certain increasing vehemence. Holroyd took up the field-glass and resumed his scrutiny, first of the ants and then of the dead man amidships.

He has described these ants to me very particularly.
