has returned to the entomologival work under Dr, W, D. Hunter. U. C. 
Loftin and W.K. Hanson are still connected with the Board and have 
been engaged in part in the rreparation of the meas on the work in 
the Laguna covering the last two years, 
Mr, Loftin wes commissioned early in this vear to make an inves- 
tigation of the insect pests of cotton in Porto Rico, mpre patttablathly 
to determine whether it would be advisable to permit Porto Rican cot- 
ton seed to come to the United Stetes for milling, In the course of 
this work he also investigated the cotton situation in Santo Domingo 
at the request of the Santo Domingo Government, No pink bollworm was 
found cither in Porto Rico or in Santo Domingo, but a large list of 
other cotton insects, most of them well-known enemies of this plant, 
were collected. A cotton blister mite howaéver, was found which is not 
known to occur in the United States; and the occurrence also of cer- 
tain cotton diseases in the Island, notably, an internal boll disease 
which seers to be widely distributed throughout the West Indies and 
is probably new to the United States, would seem to indicate the un- 
desirability of permitting movement of the cotton seed referred to 
above, 
The increasing traffic with Mexico at El Paso has made it nec- 
essary to take steps to increase the one-car fumigation house at that 
point to a fifteen-car house. E.R, Sasscer has recently been on the 
Mexican border looking into the matter of enlargement of the fumiga- 
tion plant and the general situation. There is also under considera~ 
tion the establishment of a similar car-fumigation house at Nogales. 
The quarantine as to Mexican corn has resulted in the erection of a 
plant for the disinfection of corn at Piedras Negras opposite Eagle 
Pass. Similar disinfecting plants are being considered and may la- 
ter be established at El Paso, Brownsville, Del Rio, and perhaps oth- 
er points on the border, Under the quarantine all Mexican corn must 
either be disinfected or ground to the fineness of meal, At the pres- 
ent time most of such corn is being ground. 
Los Angeles is now preparing to compete as a port of entry for 
foreign corn and other grains with San Francisco and Seattle. Plans 
are under way for the erection at the port of Los Angeles of a vacuum 
fumigation plant for South Afterican and other foreign cotton aa a 
corn sterilization plant for Mexican and Oriental corn.
