spring rise of the river threatened to sweep awa ay his cabin, when 
he took to his canoe, and dropped down the stream among the float- 
ing logs and masses sofice. In 1844 he returned to Old Prussia on 
isit, at Kénigsberg made the acquaintance of Ernst Meyer, the 
Poiteisor of Botany, and learned from him—what he would have 
een most glad to know before—that dried ape oimens. of plants for 
the herbarium night be disposed of at a reasonable price. Return- 
ing to St. Louis, he began to collect plants in this view, took the 
specimens to Dr. ngelmann, who gave him botanical assistance 
; w 
remained for about a year, and made his well-known New Mext- 
can collection, the first fruits of the botany of that interesting 
district. In 1849, he attempted another western botanical expe 
dition, thie | time with Salt Lake in view. But on the plains he 
lost all his drying paper in a flood of the Little Blue River, and 
he returned to St. Louis, to find that all his collections, books, 
journals and oes possessions had been burnt in the great con fla- 
gration which had just devastated that city. He n now sought a 
different climate, and, at the approach of winter, went to the 
Isthmus of Panama for four months, made at Chagres an inter 
esting botanical collection, returned by way of New Orleans to 
Arkansas, and to Me emphis on the Tennessee side of the river 
where for three years he carried on the camphene-light business, 
botanizing in the vicinity when be could. In 1854, the introduc 
tion of gas having made his occupation unprofitable, and a 
craving for new scenes being strong upon him, he sailed f 
for seven years (except one winter phicti'g in the Nether at 
Cambridge), having the companionship and assistance of a half 
brother who had joined him, and whom, being rather feeble-minded, 
he took care of for the rest of his life. In 1871, having sold 
his place in Missouri, he returned again to Prussia, intending 
to remain in his native country. But he soon longed for the 
New World, to which he returned in 1873; he settled 1%
