Descriptions of Eight New Varieties of Prairie Roses. 353 



France from Peru, S. A., in 1684: in its original state, it is 

 said to be found growing to a considerable height, forming 

 quite a tree. 



I cannot refrain from expressing the most earnest wishes 

 for the success of our enterprise in establishing an Experi- 

 mental Garden in Florida, for the cultivation and acclima- 

 tion of tropica] plants. The feasibility of the plan is so clear 

 that the national advantages derived therefrom cannot but 

 strongly impress the public with the ulterior benefits which 

 will grow out of its foimdation when brought to maturity. 

 As it will be the means of introducing many of the most val- 

 uable plants of the tropics from distant regions, promoting 

 agricultural science, increasing the original material of our 

 manufactures, adding largely to our staple commodities and 

 commercial exports, and, above all, diffusing a love for the 

 cultivation of plants in the rising generation, that will perma- 

 nently base and characterize us as an agricultural nation. 

 With great esteem, I am, dear sir, very respectfully yours, 



Augustus Mitchell, M.D. 



Hon. H. a, S. Dearborn. 



We have already expressed our opinion of Dr. Mitchell's 

 papers, which possess great value, and we are gratified in be- 

 ing the medium of communication, through General Dearborn, 

 of his letters. For his complimentary notice of our labors in 

 the science of Horticulture, we feel highly honored. Another 

 excellent letter is postponed, for want of room, to our next.

 roses have gone. Mr. Feast, who was the first to give a 

 new feature to our native Prairie, deserves the thanks of
