 138, Dec. 1908; plates). — The method of growing tobacco under the

 U.S.A. Department of Agriculture conducted a joint experiment in this 

 direction, and eventually tobacco was produced from Sumatra seed 

 equal, if not superior, to any imported from the island of Sumatra. 

 Great hopes of a new era of prosperity in Connecticut were immediately 

 aroused, and the area devoted to the new industry rose from 41 acres 

 in 1901 to 700 acres in 1902. Then came a bad season, the crop was a 

 failure and many farmers were ruined. Those who were able to tide

 thinking that the poor quality of their tobacco had been due merely to 

 the unfavourable season. The results were perhaps even more unsatis-
