^T. 31.] TO GEORGE ENGELMANN. 291 



ure of spending a week with him not long since, and 

 hope to visit him again early in the autumn. I shall 

 miss him very much. I am here more favorably situ- 

 ated with respect to books than at New York. I hope 

 next week to begin again with the " Flora," and per- 

 haps to finish the Monopetalae. 



TO GEORGE ENGELMANN. 



CAMBRIDGE, 26th July, 1842. 



MY DEAR DOCTOR, I hope to get settled here, 

 and in working order in a week or so ; to work at 

 Compositae all next month, and to occupy a part of 

 September and October in collecting the roots and 

 seeds of plants, of the White Mountains, of western 

 New York, etc., for our Botanic Garden here ; which 

 I wish to renovate, to make creditable to the country 

 and subservient to the advancement of our favorite 

 science. I wish to see growing here all the hardy 

 and half-hardy plants of the United States (as well 

 as many exotics, etc.), and shall exert myself stren- 

 uously for their introduction. The Garden contains 

 seven acres ; the trees and shrubs are well grown up ; 

 we are free from debt, and have a small fund. The 

 people and the corporation are anxious that we should 

 do something, and I trust will second our efforts. 



Allow me therefore to say that yourself and your 

 friend Lindheimer 1 in Texas would render me, and 

 also the cause of botany in this country, the greatest 

 aid (which I will take every opportunity of publicly 

 acknowledging), if you will send me roots or seeds of 



1 Ferdinand Lindheimer, 1801-1879. Died at New Braunfels, 

 Texas. A German. " An assiduous and excellent collector and a keen 

 observer ; his notes, full and discriminating, add not a Httle to the 

 value of the collections " [A. G.].
