"No, from Boston. At least that is where you are to meet Mr. Roote. Rather a full review of the mackerel fishery has been made, so I sup

pose this is some special inquiry. The regular statistics of Boston and Gloucester fish-markets are so important that local agents are appointed to make monthly reports. You have not been called on much for extra collecting recently, have you?"

"No, sir," answered Colin; "almost all the research workers have enough specimens for the work they're doing, because it's too near the end of the time to start any new details. So I haven't much to do except to look after the trap."

"We'll get a few days together on the oyster drill, then," said the director, "before you go away."

When the time came for Colin to leave Woods Hole he found himself most reluctant to go, and he rather regretted that he had accepted the mackerel fishery investigation, because he saw that he could have got permission to work on with Mr. Prelatt for a week or two. But the matter had been arranged, and when the boy arrived in Boston, he was alert with the interest of a new experience.

The statistician was a silent man. He greeted Colin with few words and eyed him critically.

"Hm! You can handle a boat?"

"Yes, sir," said Colin in surprise.

"Get aboard the Shiner at seven-thirty to-morrow, at the dock next to Gray's," and he nodded his head and walked off, leaving Colin to stare after him.
