II. Plant Picture Collection. This collection has 

 developed into an important adjunct of the museum system. 

 The acquisition of the Lyon collection of plant pictures and 

 its incorporation with the nucleus of a similar collection de- 

 scribed in my last annual report furnishes an ample supply of 

 good plates to draw upon for museum purposes, and fortu- 

 nately, just at a time when we especially need them. The 

 Garden was fortunate in being able to secure the Lyon col- 

 lection, which is made up of both black-and-white and col- 

 ored plates from many of the standard botanical works of 

 the United States, Great Britain and continental Europe. It 

 is estimated to contain 265,000 plates, many of which are ac- 

 companied by the original letterpress; this matter together 

 with the plates to which it belongs will in many cases be of 

 great value when incorporated in the herbarium.
