A. DR. GRAY'S WILL. 



DR. GRAY in his will left to the herbarium the proceeds 

 of all his copyrights. His strong belief in the importance 

 of a large and well-kept herbarium, as an establishment 

 indispensable not only to the development of botanical 

 studies at Harvard but also to the diffusion throughout the 

 whole country of a knowledge of its flora, is shown by this 

 bequest, and also by the active efforts he was constantly 

 making in its behalf during his life and by the personal 

 sacrifices to which he cheerfully submitted, that the herba- 

 rium might profit. Some of the difficulties in the develop- 

 ment of his cherished project will already have suggested 

 themselves to the reader of these pages. Others may be 

 touched upon briefly here. 



The reputation of Dr. Gray at home and abroad natu- 

 rally served to draw to the herbarium large numbers of 

 specimens, and the number was increased by the purchases 

 which he contrived to make from time to time, either from 

 his own scanty means, or from the occasional gifts of friends. 

 The storing of his large and valuable collections in the small 

 house in the garden where he lived was attended by so 

 much danger of destruction by fire that he offered to present 

 the collection to Harvard University, if a suitable building 

 for its reception were provided ; and, greatly to his relief, 

 his herbarium was transferred in 1864 to the new fire-proof 

 building, for whose construction twelve thousand dollars 

 were given by his liberal friend, Mr. Nathaniel Thayer. 



If Dr. Gray was able during his life to secure a building 

 which at the time of its completion seemed ample for its 

 purpose, he was less fortunate in his efforts to obtain a
