ten years to again become very destructive. This last destructive 
outbreak reached its maximum, I think, about four or five years ago, 
whereupon the scale again almost entirely disappeared for a year or 
two, but at the present time is again increasing in numbers. Hymen - 
opterous parasites seem to be responsible for this irregularity in the 
fortunes of the insect. 
At this point, the meeting of the Association adjourned and the 
Section on Horticultural Inspection convened.

The Section on Horticultural Inspection met in the Soldan High 
School, St. Louis, Mo., January 1, 1920, at 1:30 p. m., for a single after¬ 
noon session. 
In order to conserve time, the chairman, E. C. Cotton, dispensed 
with his address, and after preliminary remarks called for the first 
paper: 
1. “ Treating Nursery Stock for the Control of San Jose Scale,” 
which was read by Mr. K. C. Sullivan, and briefly commented on by 
some of the members. 
2. “The Present Status of Aleurocanthus woglumi Ashby in the 
Panama Canal Zone” was not given by Mr. H. F. Dietz, owing to his 
earlier withdrawal from the U. S. Bureau of Entomology, but Mr. C. 
L. Marlatt stated that this paper would, in all probability, be published 
as a bulletin of the Federal Department. 
3. The paper on “Important Foreign Insect Pests Collected on 
Imported Nursery Stock in 1919” was read by Mr. E. R. Sasscer, and 
discussed by the members present. 
Mr. E. E. Scholl stated that the horticultural associations of Texas 
strongly urged that federal port of entry inspection be established at 
Galveston. Report was made that federal funds for this purpose had 
been asked for by the Federal Horticultural Board. 
4. The paper on “The Japanese Beetle Problem” was read by Mr. 
J. J. Davis, and a number of very interesting and instructive slides 
were shown. Discussion followed. 
5. The paper on “The Japanese Beetle Quarantine Work” by C. H. 
Hadley was omitted, on account of his absence from the meeting. 
6. The interesting and very instructive report by Mr. C. L. Marlatt, 
chairman of the Federal Horticultural Board, on “Federal Plant 
Quarantine Work and Cooperation with State Officials” was listened 
to with the greatest interest by everyone present, on account of the
