In a little while Mr. and Mrs. Brown were sipping the hot coffee while Bunny and Sue were drinking warm milk. No, it was not real, fresh milk, for the milkman did not stop at Cocoanut Island and there were no cows on it, so far as the castaways knew. But in the boat were cans of evaporated milk, and when this had been warmed with a little hot water it made a good drink for the children.
