140 THE PERIODICAL CICADA. 
SEVENTEEN-YEAR BROOD VIII, 1889. 
A very large quantity of egg-bearing twigs of this brood were received 
at the Department from various sources in the summer of 1889 and dis- 
tributed under oak and other trees on the grounds of the Department 
of Agriculture. 
On July 19 a quantity of eggs were received from Mr. H. W. Beeves, 
of Lebanon, Ky. These were about hatching and were distributed 
around the base of a large red-oak tree marked X; the others were 
placed about a burr oak similarly marked od a branch. The latter tree 
was newly marked April 15, 1897, the limb bearing the old mark having 
been removed. On the same date, July 19, some eggs were received 
from Mineral Springs, Ohio, and placed about the following trees: Two 
white-oak trees, marked X on a branch; one oak tree (Q. coccinea), 
marked X on the trunk; one Q. obtusiloba, similarly marked. 
July 26 another lot of eggs was received from Mr. C. J. Oowles, of 
Wilkesboro, X. 0. Many of the eggs had already hatched and the 
young larvad were running about in the barrel when received. The 
twigs, eggs, and larva) were all distributed together about three oak 
trees, standing in a triangle, two of which are marked XX and one 
marked XXX. 
Juty 27 another lot of eggs was received from Mr. J. B. Lewis, of 
Eubanks, Ky. These were placed about a sycamore tree, marked on 
the upper side of the .branch with an X. On the same date a lot of 
eggs were received from Xorth Carolina, taken from the following 
trees: Apple, peach, plum, pear, chinquapin oak, black oak, white oak, 
cedar, spruce, mimosa, holly, and sourwood. These eggs were placed 
under two willow trees, surrounding the trunks to a distance of 2 or 
3 feet, and under Salix basfordiana and Salix sp., both marked with 
an X. The eggs were hatching when distributed. 
July 19 an additional lot of eggs were received from Mineral Springs, 
Ohio, and were strewn about the base of three white-oak trees, marked 
XXXI on the trunk, and about two other oaks (Q. prinos), similarly 
marked. 
August 2 Mr. D. P. Cook sent a few branches with eggs from Long 
Island, X. Y., which were placed about the base of a small red-oak 
tree marked X. The eggs were unhatched when received and the tree 
has since been removed. 
The vast quantity of the eggs and young larvse represented in the 
above plantings make the probability of a successful outcome of this 
experiment much greater than any of the earlier ones. As we have 
already indicated, examinations were made at long-time intervals only, 
the first being made by the writer October 17, 1893, and was of the 
material sent by Mr. C. J. Cowles, of Wilkesboro, X. C. A very small 
excavation under one of the trees mentioned resulted in securing 
twenty-three small larva; and six of the size of the 1885 brood, all 
found at depths varying from 8 to 18 inches, the 1889 brood ranging
