On the 1st of May, the observatory was set up, and the astronomical
quadrant, together with some other instruments, was taken on shore.
When, on the next morning, Mr. Cook and Mr. Green landed for the
purpose of fixing the quadrant in a situation for use, to their
inexpressible surprise and concern it was not to be found. It had been
deposited in a tent reserved for the lieutenant's use, where no one
had slept; it had never been taken out of the packing case, and the
whole was of considerable weight: none of the other instruments were
missing; and a sentinel had been posted the whole night within five
yards of the tent. These circumstances induced a suspicion that the
robbery might have been committed by some of our own people, who
having seen a deal box, and not knowing the contents, might imagine
that it contained nails, or other articles for traffic with the
natives. The most diligent search, therefore, was made, and a large
reward was offered for the finding of the quadrant, but with no degree

this gentleman had more influence over the Indians than any other
person on board the Endeavour, and as there could be little doubt of
the quadrant's having been conveyed away by some of the natives, he
determined to go in search of it into the woods; and it was recovered
in consequence of his judicious and spirited exertions. The pleasure
with which it was brought back was equal to the importance of the
event; for the grand object of the voyage could not otherwise have
been accomplished.

Another embarrassment, though not of so serious a nature, was
occasioned, on the very same day, by one of our officers having
inadvertently taken into custody Tootahah, a chief, who had connected
himself in the most friendly manner with the English. Lieutenant Cook,
who had given express orders that none of the Indians should be
