particular case, had saved his crop and was, therefore, an economic: 
proposition. 
AMERICAN BOLL WORM. 
In reply to Mr. Ritchie, Mr. Parnell stated that he was rather 
sceptical as to the efficacy of maize as a trap crop for the American 
Cotton Boll worm. 
Mr. RITCHIE stated that, in Tanganyika no Chloridea was found 
on cotton bolls after June: there was only one generation on cotton 
bolls in the year. The place of Chloridea on maize was taken by a 
species of Diatraea. 
IMPORTATION OF SEED.* 
Mr. MILLIGAN said that the consensus of opinion was that it 
must be impressed on all countries how dangerous it was to admit 
seed on certificate only. 
Mr. PARNELL thought that there was no need to import cotton 
seed in bulk as small quantities, properly disinfected, were sufficient 
to produce, in a few years, the quantity necessary. 
Mr. KIRBY intimated that the present best method for 
Tanganyika was to import in bulk from countries from which there 
was little risk of the introduction of pests. The Tanganyika importa- 
tions were entirely from Uganda. 
Mr. HARDENBERG agreed with Mr. Kirby that bulk importation 
of seed must be allowed in certain cases in new countries, otherwise 
hardship might be caused to planters. 
Mr. WORTLEY thought that the risk involved in bulk importa- 
tions was far too great. 
CONTROL OF NATIVE COTTON INDUSTRY. 
The CHAIRMAN (Mr. Fuller) then read two paperst submitted 
by Mr. Sampson (T.C.(C)Cot.1 and T.C.(C)Cot.2). 
Mr. SIMPSON said that in the early days in Uganda seed cotton 
from Bukoba was allowed to be ginned at an isolated spot near 
Entebbe; also before ginneries were erected in Kenya, Kenya cotton 
had been ginned in Uganda. Nowadays, no seed cotton was coming 
in, only baled cotton from Kenya and the Congo passed through ‘‘ in 
transit ©’ on permit, if properly pressed and baled. He thought that 
if workers could not keep in touch by correspondence, visits should be 
paid to those territories where the desired information could be 
obtained. 
Mr. KIRBY supported the idea that it was the duty of officers to 
keep themselves informed as to what was happening in other places. 
CONTROL OF GINNERIES. 
The CHAIRMAN (Mr. Fuller) read Mr. Sampson's paper! 
(T.C.(C)Cot.7) on the control of ginneries, with special reference to 
the spread of disease.
