"Would you really do that for me?" asked Colin.

"Very gladly," was the reply; "but you will need a series almost twice as large as you haf now in order to make it of any value."

"Indeed I'll complete the series, Dr. Edelstein," Colin said. "I'll work at it every minute of spare time I can get."

From that moment time seemed to Colin all too short—the days appeared to fly. He was up long before breakfast getting out specimens both for himself and his chief and till late in the evening he would sit over his microscope working out the details of his experiments. The expert, who had realized earlier in the summer that Colin was restless, now saw that the reason was that none of the work he had been given to do possessed an individual note, and perceiving—as did every one—the enthusiastic nature of the lad, he helped him in every way possible. Thus it came about that be

fore the day set for the reopening of college, Colin had finished the series of experiments which had been thought necessary, and had sent the manuscript of his article to Washington. And in the very first batch of letters that he received on his arrival at college was one from the Commissioner accepting his report and promising publication in the Bulletin.

Colin ever afterward declared that this was a great stimulus during his college work. He had done well the first year, but his late training under Dr. Edelstein and the spur of research had taught him how to concentrate upon his studies. He did not neglect the out-of-doors life, however, and he still had the swimming championship to defend, but every minute that he was not actively at play he was hard at work. Idle minutes were scarce. Nor did he fail of his reward. Just before the spring examination he received a letter from the Bureau of Fisheries telling him that his application for the next summer had been accepted and assigning him to duty at Woods Hole, the station where he had long desired to be.

Immediately after the close of the college year, and a few weeks spent at home, Colin betook himself to Washington, where he received the nec

essary credentials. As still a week intervened before the time of the opening of the laboratory, he spent several days in New York, visiting the American Museum daily and assisting his friend, Mr. Collier, with whom he had gone to Bermuda. The sea-garden exhibits were all completed and were among the museum's most popular cases, and the curator was engaged in preparing some exquisite models of the Radiolaria, those magical creatures of the sea, which are so small that they can be seen only with a powerful microscope, but which look like living snow-crystals, although a thousand times more beautiful. Some were already installed in the museum, but a large series was planned.

On his arrival at Woods Hole, Colin found work in the hatchery division of the station almost at an end. Hundreds of millions of cod, pollock, haddock, and flatfish fry had been hatched from eggs and planted in favorable places for their further development, and tens of millions of lobster fry as well. A few of the hatching troughs were in use, but most of them had been emptied and prepared for the work of the biological department of the Bureau, to which the station was given over during the summer months.
