permanent fund for the maintenance of the collection. In 

 1864, the sum of $10,000 - $12.000 was raised by friends 

 for its support ; but the interest of all the available funds 

 was far short of what was necessary for the proper payment 

 of a curator, for necessary purchases of plants and books 

 and for running expenses. In fact, during his lifetime, run- 

 ning expenses could not have been met had it not been for 

 occasional gifts from friends of the herbarium, including, 

 for several years, a grant from the Massachusetts Society for 

 the Promotion of Agriculture. The bequest in his will was 

 an attempt on his part to replace, as far as he was able, the 

 sums obtained by him annually from various sources during 

 his life. But even with the amount derived from the copy- 

 rights, which must, of necessity, diminish in future years, 

 the endowments of the herbarium are by no means sufficient 

 to provide for its maintenance, even on the present scale. 

 At the time of the transfer in 1864, the herbarium contained 

 at least two hundred thousand specimens, and the library 

 between two and three thousand works. Both have in- 

 creased largely since that date.
