"I don't see anything of the _Swallow_, or of any other ship," came from Dave, after he had gazed around for several minutes. "The ship is probably in the vicinity of that other island." From the top of the hill they could see that the island was uninhabited. Whether or not any wild beasts outside of the gorilla were located there they could not determine. "I hope we don't have to stay here too long," remarked the young diver, as they started back for the spot where they had left Bob and Stoodles. "We'll have to stay until we find the ship." Halfway down the side of the hill Captain Broadbeam gave a sudden leap into the air. "Look out!" he screamed. "What's the matter?" queried Dave. "Spiders! As big as your hand!" The master of the _Swallow_ was right. He had stepped on a mound which was a spiders' nest, and out from the soil issued ten or a dozen big brown and yellow spiders, most ferocious in their appearance. The creatures made after both the captain and Dave, and both lost no time in putting a good distance between themselves and that vicinity. "Gosh! I never saw such spiders in my life!" gasped Dave, when he thought himself safe. "They certainly were large, Dave. But such things grow big in the tropics." "They looked as if they might be poisonous." "They are. We must watch out for them in the future." Not long after this they came to a spot where a number of bushes were growing, covered with large, oval-shaped berries. "These berries are perfectly good and very nourishing," said the captain. "Let us pick a quantity and take them back to the camp." Back of the patch of berries was a fine spring and here they procured a cold drink of water. Just below the spring was a wide pool several feet deep, and in this pool numerous small lizards were darting around. "Everything is full of life in the tropics," remarked the young diver. "Just look at the birds and fish, and lizards and spiders, and a hundred and one other things!" "Yes, and the vegetation is very plentiful," added the captain. They were still some distance from the shore when Dave called a halt. "Look at the big birds yonder," he whispered. "Can't we bring down two or three with sticks or stones? They will make fine eating." "We can try it, Dave." Sticks and stones were handy, and arming themselves they approached a large tree upon which the birds were resting. "Ready?" asked Dave. "Yes." "Throw!" The youth let fly a short stick and the captain a sharp stone. Down came two birds, one dead and the other seriously wounded. The others set up a wild squawking and flew away. "Not so bad!" cried the captain, and ran to dispatch the wounded bird. As he stooped over the bird there was a strange cry from another tree close by and then a whir through the air. "The gorilla!" ejaculated Dave. "Look out!"
