No. 17.] AGRICULTURAL COLLEGE. 89 



I would also call your attention to the fact that we need a green- 

 house and conservatory, for the propagation and preservation of 

 flowering plants. 



I have placed these needs in the order of their importance, and 

 would respectfully urge that efforts be made for providing, at least 

 the Garden-house before mentioned. 



BOTANY. 



The Sophomore and Junior classes pursued this subject as laid 

 down in the course of study, both classes doing their work in a 

 thorough and satisfactory manner. In the first mentioned class col- 

 lections of plants were made amounting in the aggregate to upwards 

 of two thousand specimens; these were neatly mounted in suitable 

 books, correctly named, and preserved for further study next year. 



During the past two years I have been endeavoring to make a full 

 collection of the plants of this locality, but for want of time have 

 not yet been able to do so. This season we added quite materially 

 to the Herbarium both by exchange and purchase, and now have 

 representatives of perhaps about twenty-five hundred species. There 

 should be some provision made for an annual addition of at least a 

 thousand species, which would in a few years give us a good sized 

 and valuable collection. 



I append below, a list of plants, as a contribution to the Flora of 

 Iowa. The list is necessarily imperfect, in omitting many plants 

 known to be native of Iowa, but which for lack of time to fully 

 identify have been left out. In collecting the material for the list I 

 have been greatly aided by Mr. J. C. Arthur, of the Junior class, 

 and am under many obligations to Professor Carpenter, of Indianola, 

 Professor McLain, of Fayette, and Professor Parker, late of Grin, 

 nell, (now of Amherst, Mass.,) for lists of plants found in their re- 

 spective localities. 



Bev. Isaiah Peid, of iSTevada, also furnished me with a partial list 

 of the plants collected by him several years ago in the vicinity of 

 Burlington. 



All of which is respectfully submitted.
