CHRONOLOGICAL ACCOUNT OF DIFFERENT BROODS. 25 
extent of the brood as given by Dr. Smith and Dr. Phares, Carthage 
being east of the dividing ridge of the State of Mississippi. 
Broop VII.—Tredecim—1872, 1885. 
In the year 1872, and at intervals of thirteen years thereafter, they will in all proba- 
bility appear in Jackson County and around Cobden and Jonesborough, in Union 
County, southern Illinois, in Kansas, Missouri, Georgia, Louisiana, Tennessee, and 
Mississippi. 
According to Mr. Paul Frick, of Jonesborough, they were in Union County, Illinois, 
in 1858, and he also thinks it was a great year for them «about 1832. Those of 1858 
were probably premature stragglers of the 1859 brood, while Mr. Frick is most likely 
mistaken as to the year 1832, since the Rev. George W. Ferrell, of Cobden, Union 
County, witnessed their appearance at that place in 1833, and also in 1846 and 1859; 
and Cyrus Thomas has also recorded their appearance in 1859 in the fifth report of the 
Illinois State Agricultural Society, page 458,* while a paragraph in the Baltimore 
(Md.) Sun of June 13, 1859, says, ‘‘ The locusts have made their appearance in ‘Egypt,’ 
in sonthern I]limtois, and cover woods and orchards in swarms.” This brood not im- 
probably extends westward into Missouri, for several of the old settlers around 
Eureka, in Saint Louis County, Missouri, recollect it being ‘locust year” about the 
time of its last appearance, while Mr. L. D. Votaw, of Eureka, and William Muir, of 
Fox Creek, Mo., both believe it was exactly nine years ago, or in the year 1859. Dr. 
Smith records it in DeKalb, Gwinnett, and Newton Counties, Georgia, in 1846 and 
1859; in the northern part of Tennessee also, in 1846 and 1859; in the whole eastern 
portion of Mississippi, from the ridge which is 45 miles from the river, on the west, to 
the eastern boundary, in 1820, 1833, 12846, and 1859; in Carroll Parish, Louisiana, in 
1859 ; and in Phillips County, Kansas, in the same year. 
By referring to Brood XV, it will be seen that in 1846, or during the first year of 
’ the Mexican war, this 15-year brood appeared simultaneously with a 17-year brood in 
western Pennsylvania and Ohio. 
1872.—For this year we have records of the reappearance of this brood 
from the following localities: In southern Illinois it appeared in Union 
County, as witnessed by a correspondent of the Saint Louis Republican 
who writes, on May 31, 1871, from Cobden: ‘ This section of country is 
quite lively and animated at present, a great portion of the life being 
supplied by the locusts, whose shrill monotone meets and oppresses the 
ear in all directions. There is no escaping that tiresome tune, and we 
ean only wish, vainly enough, that the noisy insects would introduce 
some variations into their ceaseless song. During the past week they 
have been coming out of the ground in myriads, and the trees are loaded 
with them, as they deposit their eggs in the bark of the young and 
tender branches.” Another correspondent from ‘ Egypt,” of the same 
county, states that the locusts have appeared there true to prediction ; 
that the woods are now ringing with their song, and that he knows of 
the appearance of the brood in 1846 and 1859. Among my own corre- 
spondents, Mr. Parker Earle (letter dated May 25, 1872) and Mr. 8. H. 
Beckwith, of South Pass, stated that they abounded at Cobden, Union 
*If Mr. Paul Frick is correct, the brood he bas witnessed may possibly be a detachment of the 
Mississippi and Louisiana Brood VI; in which case the Cicadas appear for two consecutive years in 
Union County, Illinois, as they do (see Broods XII and XIV) in central Ohio, and portions of north- 
western Missouri.
