188 Miscellanies. 



nent. He is one of a considerable number of gentlemen to whom 

 the country is much indebted for this species of information, gained 

 by no small share of toil, privation and danger, in adventures of ob- 

 servation and discovery in the less explored parts of North America. 



18. Science in the South. — Among the literary institutions that have 

 been established in the Southern States, the university of Tuscaloosa 

 appears to be one of the best endowed and one of the most promis- 

 ing. Its president, the Rev. Alva Woods, pronounced, in June, a 

 valuable discourse before the lyceum of Tuscaloosa, an institution 

 designed, like others of its name, to diffuse useful knowledge as ex- 

 tensively as possible among the people.

1. Remarks on the American Locust, (Cicada Septendecem,) hy 

 David Thomas. — The locusts have appeared in great numbers this 

 season, along the shores of the Cayuga lake ; but I have not yet as- 

 certained the boundaries of their district. To the east, they were 

 found at Onondaga, and as far to the west as Genesee river. It is 

 probable, however, that they extended farther in both directions. 



One remarkable fact in the history of this insect, I have not seen 

 noticed in the course of my reading, viz. in different parts of our 

 country, it comes forth in different years. Thus, it appeared in the 

 western states in 1829;* in the western part of New York in 1831 ; 

 and in the eastern part of Pennsylvania in 1800, corresponding with 

 1817 and 1834. Another district has been mentioned to me by dif- 

 ferent persons, but the year has not been ascertained. 



A map of the United States, shewing the boundaries of such dis- 

 tricts, and marked with the years in which these insects come forth, 

 would be an interesting present to entomologists ; and if each friend 

 of science who subscribes for this Journal would contribute his mite, 

 it might speedily be completed. 



Oak lands seem the favorite residence of this insect. It is doubt- 

 ful if it ever inhabits beech and maple lands in a state of nature, but 

 since the forests have been partially removed, it is evidently extend- 

 ing its limits. ■ ;
