soon made it over to Columbia College. In 1810 he made a 

 voyage to the West Indies for the recovery of his health. 

 Returning in the autumn of 1811, he landed at Wiscasset, 

 in Maine, and " had an opportunity of visiting Professor 

 Peck, of Cambridge College, near Boston," and of seeing 

 the alpine plants which Peck had collected on the White 

 Mountains. 



The plants collected by Lewis and Clark, on their 

 return from the far West, were studied, described, and 

 figured by Pursh. He inserted the descriptions in his flora, 

 distinguishing them by the words : " v. s. in Herb. Lewis." 

 He also studied the collections made by Aloysius 

 Enslen, sent to America by Count Lichtenstein, of Austria, 

 which fitted up a desideratum in his collection, particularly 

 in the plants of Lower Louisiana and Georgia. " v. s. in Herb 

 Enslen." At the same time he had frequent opportunities of 

 seeing the herbarium and collection of living plants of Mr. 

 John Lyon, a gentleman, through whose industry and skill, 

 more new and rare American plants have lately been 

 sent into Europe than through any other channel 

 whatever. " v. s. in Herb. Lyon." 



At the end of 1811, or in 1812, he went to England 

 with his collections and notes ; and at the close of 1813, 

 consulting, the while, the herbaria of Clayton, Pallas, 

 Plukenet, Catesby, Morison, Sherard, Walter, and that of 

 Banks.*
