While we lay in this harbour, we carried ashore the bread, remaining in the bread-room, to clear it of vermin. The number of cock-roaches that infested the ship at this time is incredible. The damage they did us was very considerable; and every method devised by us to destroy them proved ineffectual. These animals, which, at first, were a nuisance, like all other insects, had now become a real pest; and so destructive, that few things were free from their ravages. If food of any kind was exposed only for a few minutes, it was covered with them; and they soon pierced it full of holes resembling a honeycomb. They were particularly destructive to birds, which had been stuffed and preserved as curiosities; and, what was worse, were uncommonly fond of ink; so that the writing on the labels, fastened to different articles, was quite eaten out; and the only thing that preserved books from them, was the closeness of the binding, which prevented these devourers getting between the leaves. According to Mr. Anderson’s observations, they were of two sorts, the _blatta orientalis_ and _germanica_. The first of these had been carried home in the ship from her former voyage, where they withstood the severity of the hard winter in 1776, though she was in dock all the time. The others had only made their appearance since our leaving New Zealand; but had increased so fast, that they now not only did all the mischief mentioned above, but had even got amongst the rigging; so that when a sail was loosened, thousands of them fell upon the decks. The _orientales_, though in infinite numbers, scarcely came out but in the night, when they made every thing in the cabins seem as if in motion, from the particular noise in crawling about. And, besides their disagreeable appearance, they did great mischief to our bread, which was so bespattered with their excrement, that it would have been badly relished by delicate feeders.
The intercourse of trade and friendly offices was carried on between us and the natives without being disturbed by any one accident till the evening of the 22d, when a man found means to get into Mr. Bayly’s observatory, and to carry off a sextant unobserved. As soon as I was made acquainted with the theft, I went ashore, and got Omai to apply to the chiefs, to procure restitution. He did so; but they took no steps toward it, being more attentive to a _heeva_ that was then acting, till I ordered the performers of the exhibition to desist. They were now convinced, that I was in earnest, and began to make some enquiry after the thief, who was sitting in the midst of them quite unconcerned, inasmuch that I was in great doubt of his being the guilty person; especially as he denied it. Omai, however, assuring me that he was the man, I sent him on board the ship, and there confined him. This raised a general ferment amongst the assembled natives; and the whole body fled, in spite of all my endeavours to stop them. Having employed Omai to examine the prisoner, with some difficulty he was brought to confess where he had laid the sextant; but, as it was now dark, he could not find it till day-light the next morning, when it was brought back unhurt. After this, the natives recovered from their fright, and began to gather about us as usual. And as to the thief, he appearing to be a hardened scoundrel, I punished him more severely than I had done any culprit before. Besides having his head and beard shaved, I ordered both his ears to be cut off, and then dismissed him.
