BOTANY AT ST. LOUIS 125 



in 1844. He also came into possession of some of Geyer's collections, 

 as it is definitely stated that they had been deposited in the Engelmann 

 herbarium. 



In 1841 Geyer went with Fremont to the J)es Moines River in Iowa 

 territory, where he found a number of new plants. In 1843 he ex- 

 plored the upper Illinois territory and formed the herbarium which 

 was first offered for sale. In 1843 he began the journey from Missouri 

 to the Pacific coast, lasting through the years 1843 and 1844. He ex- 

 plored the northwestern country very extensively and penetrated to 

 hitherto inaccessible places by accompanying missionary trains on their 

 visits to the different Indian tribes. He finally reached Fort A^an- 

 eouver, and from there sailed on November 13, 1844, for England, go- 

 ing by way of the Sandwich Islands and Cape Horn. He arrived in 

 England May 25, 1845, and spent some months at Kew, working over 

 his collections and sorting out small lots of plants to sell. A large 

 part of his profits from such sales was used in defraying expenses 

 caused by a sickness brought on by his previous hardships. In Sep- 

 tember, 1845, he again returned to his home in Saxony, after an ab- 

 sence of eleven years. At first he entered the employment of head-gar- 

 dener Lehman in Dresden, and later in the Royal Botanical Garden. 

 His wanderings had shown him the value of a home, and on August 

 24, 1846, he married Miss Emma Schulze. Besides his duties for the 

 garden he taught students the English language, his pupils coming 

 from every class in Meissen. Geyer also took a prominent part in the 

 local society for the advancement of science. During the last three 

 years of his life he was editor of Chronik des Gartenwesens und 

 Feuilleton der Isis, a periodical published at Meissen on the first and 

 fifteenth of the month, from January 1, 1851, to December 15, 1853. 

 Geyer's death occurred just before the end of the third volume, and it 

 was discontinued with the third volume. While in no wise neglecting 

 his duties at the garden, he came in written communication with the 

 prominent botanists of the time and rounded out his collections. 

 Heart disease troubled him considerably in his latter days and finally 

 caused his death on November 21, 1853. 



In 1835 a physician, George Engelmann by name, settled in St. 

 Louis and soon built up a lucrative practise. During his spare mo- 

 ments he worked upon botanical problems, and before long he had 

 established a reputation among botanists such that at his death he was 

 ranked among the foremost of botanical workers.
