Colin found that he was not unknown to the director, who, being especially interested in mollusks, had read the lad's paper on the mussel-shells. Accordingly he was quite heartily welcomed and set right at work.

"You will take charge of the fish-trap crew, Dare," he was informed, the director's quick, snappy eye taking in the lad. "I suppose you know enough about fish to tell the various species apart?"

"I'm not sure, sir," said the boy, "but I think I know most of the common kinds. That is, theoretically, Mr. Prelatt, through studying them. I have never done any fishing of consequence off the New England coast."

"You can haul the trap at slack water this afternoon," the director said. "I will ask Mr. Wadreds to go with you. He knows every kind of fish that swims and more about each one than three or four of the rest of us put together."

"What will be my duties, sir?" asked Colin. "I don't want to trouble you, but if I am to take charge of the crew I ought to know what I have to do."

"The trap is to be hauled daily," was the reply, "except when the water is very rough. You

will be given a list of the needs of the laboratory for experimental purposes, and as far as possible, you will fill those needs. Sometimes you may have to assist in the collecting trip besides, as for green sea-urchins and the like; or perhaps you may have to draw a seine for silversides and small fish. Sometimes you may be needed to haul some of the lobster pots, because we shall have two men at least doing research work on lobsters. Again, you may have to get mussels for some work that is being done on shellfish for food. There will be two other students working with you in maintaining the supply of specimen material, under the direction of the head collector."

"Very well, Mr. Prelatt," the boy replied, "I'll see that things are kept up as far as possible. Am I to come to you for information as to where to go for special fish and so forth?"

"Mr. Wadreds knows more about that than I do," the director said; "he can usually tell you just where to find anything you're after. You'll soon find it easy, because collecting narrows down to a few species. The M. B. L. boat does collecting, too, and sometimes each party is able to help the other."
