394 Report on the progress of the Horticultural Society >, 



" With Guatemala, as your centre of operations, you will have the 

 " command of a very interesting vegetation from which we expect 

 " the most valuable result. Near Guatemala is the Volcan de Agua 

 " between 12000 and 13000 feet above the sea, and clothed with 

 " verdure to the summit. The city of Guatemala itself is 5000 feet 

 " above the sea, and, therefore, the climate will be very different 

 " from that of similar latitudes so near the equator. The neigh- 

 " bouring mountains in the west should be carefully explored, and 

 " especially the side next the Pacific. 



" In all your proceedings you will bear in mind that the objects of 

 " the Society remain unaltered, and that the instructions already 

 " given you as to the kind of plants and seeds to be collected are still 

 " to be observed, viz.— that every thing beautiful or useful, not in the 

 " gardens of England, is to be sent home, whether requiring the 

 " stove, the greenhouse, or promising to be suited to the open air ; 

 " but that plants of the latter description, and consequently mountain 

 " species, are to claim your chief care." 



These instructions did not reach Mr. Hartweg till the 24th 

 January, 1839, and in the mean time he continued his monthly 

 reports, from which the following are extracts. 



No. 22.— Anganguco, September llth, 1838.—" On the 24th ult. 

 " I arrived here and found the country such as it had been described 

 " to me, the mountains being all well covered with Pines amongst 

 " which the Oyamel (Abies religiosa) is the most remarkable, but 

 " the cones not being yet ripe, I resolved to return to this place to- 

 " wards the close of this year to gather some, as well as other kinds 

 " of seeds. The herbarium is rapidly increasing here, and amounts 

 " now to about 1450 specimens." 



No. 23.— 7^ del Monte, October ISth, 1838.—" I beg to in- 

 " form you that on the 26th of last month I despatched a box 

 " marked H. S. 16, to the care of Messrs. Byrns & Co. Mexico, to 

 " be forwarded through Messrs. R. Munoz & Co. Vera Cruz, eon-
