THE FLORA OF NORTH AMERICA. 11 



Stockholm to send a bottinist to Siberia and Iceland, which aiv 

 on the same latitude as a part of Sweden, to collect seeds of plants 

 as would "improve the Swedish husbandry, gardening, man- 

 ufactures, arts, and sciences." Dr. Linnanis suggested that 

 North America would oe a better country than either. About the 

 same time a Captain Triewald gave in Stockholm an exhibition 

 and lecture on his observations on silk-culture. As Linna-us had de- 

 scribed a species of mulberry* from North America and native of 

 a climate similar to that of Sweden, this gave additional strength 

 to the choice of North America. When Count Tessin. who could 

 nearl}' always have his own wa3% and who was in favor of the 

 project, became president of the Koyal Academy, it was decided to 

 send Professor Kalrn. An appeal was sent to the three universi- 

 ties of Sweden, at Upsala, Lund, and Abo, to contribute what 

 they could for the advancement of science. Abo was the first one 

 to answer, and sent a small sum, Lund had nothing to spare, but 

 Upsala contributed liberally, considermg the times and the coun- 

 tr3^ Now-a-days, -1450 seem to us rather a small sum. With the 

 countributions from other sources, the fund amounted to about 

 twice that sum. Professor Kalm, however, spent not onh- this 

 and his own salary, but about $650 of his own money, and the 

 journey left him with very limited means for the rest of his life. 



After passports had been secured from the courts of London, 

 Paris, Madrid, and the Hague, Kalm sailed from Gothenburg the 

 11th of December, IT-tT, accompanied by Lars Jungstrom, a gar- 

 dener by profession. Overtaken by a severe storm, the vessel had 

 to put in at Grimstad, Norway, where the travelers had to stay 

 till the 8th of February', 1748. They arrived at London the 17th 

 of the same month, staj'ed in England till August 15, and arrived 

 at Philadelphia the 26th of September. 



In Philadelphia Kalm stayed about a month, and made there 

 the acquaintance of John Bartram, the most prominent American 

 naturalist at that time. Then he set out on a journey to New 

 York, passing through New Frankfort, New Bristol, Pa., Bur- 

 lington, N. J., then the residence of the governor, Trenton, 

 "Prince-town", New Brunswick, and Elizabeth, returning to Phila- 

 delphia Nov. 5. 



In November he visited Racoon, N. J., M-here a, number of

 species is not well adapted to silk-culture.
