about midnight
When four healthy boys are off on a lark of this sort the subject of eating is always one of their chief concerns , which must account for the space which it occupies in records of cruising and camping trips . Will did not go ashore that evening . Indeed , somehow , none of them cared to stay alone , though Jerry did build up quite a roaring fire , just because he was fond of seeing the flames leap up in frolic . As before , they divided the night into four watches , and this time Will chose to take the one that would bring him on deck from about midnight to two . When it came his turn he sat there holding his camera faithfully , and hoping for something to happen ; but it did not come , and he was finally forced to arouse Bluff to take his place . The latter did so rather unwillingly . Bluff was unusually sleepy , it seemed , and inclined to believe that this watch business was all humbug , anyway .
