house of facts on every subject where any desired datum lay ready to his hand.^[1] He knew every specialist in the country. Not only did he hold amicable relations with scientists actually at work, but one might think there was not a schoolboy of extraordinary genius for bird's-nesting or fishing whom he could not lay his hands on. . . If he guided the activity of others as one would use impersonal agencies in the pursuance of a definite end, he was not less exacting with himself. He not only offered freely to others, sometimes constructive rivals, the raw material of research which he collected, but in many cases he put in the hands of those whom he thought worthy, his own more or less elaborated manuscripts, to use in their investigations, thus waiving his own priority in the field. His insistence on giving full credit to collaborators of every degree, both in publication and in records, labels, and reports, was proverbial. To the tyro treading with uncertain step the entrance ways of science he was ever cordial; always a friend, guide and helper. While Professor Henry lived, the affectionate loyalty of Baird to his venerable chief was an inspiration to those about him. . . . It may be imagined that in his home life Professor Baird was altogether lovable, and we can not feel that we are laying sacrilegious hands upon the veil in saying that not the least of the benefits conferred upon American science was embodied in the influence which extended from that home upon a host of boyish students gathered from year to year under the brown towers of the Smithsonian Institution, slender as to their resources, half Bohemian as to their living, let loose with little restraint in that great disjointed village, the Washington of twenty years ago.

the splendid benevolent personality that made Professor Baird the 'grandfather of us all,'—always interested in the scientific work of young men, and always ready to give them any help possible in that direction.
