planted, some successful growers contending that the weevils are 
more injurious to shallow-planted potatoes on cloddy land than to 
deep-planted potatoes on sandy land. A note under date of August 
1 gives one infested hill among twenty-five, the infested tubers being 
an early variety and projecting from the seed bed. 
During the winter careful observations were made on the mos- 
quitoes infesting College Station and vicinity, especially from a 
sanitary standpoint. These investigations were stimulated two years 
ago when yellow fever appeared at San Antonio and seemed to be 
spreading northward. The country about College Station is low and 
level, the soil of a loamy nature, underlaid at from 6 to 10 inches with 
a tough hard clay. The streams are so rapid that they will hold 
water but a short time aftera rain. It is, therefore, the common prac- 
tice to put dams across the gulhes and collect the water during a rain- 
fall. Such tanks will rarely dry out during thesummer. It was found 
that no mosquitoes bred in such waters on account of the number of 
minnows present inall cases. The main breeding place near the college 
was at the mouth of the sewer where it empties into the brook. Here 
mosquito larve were so numerous that they formed a solid scum on 
the water. On account of the annoyance dtie to mosquitoes during the 
early spring months, making life on the campus almost unbearable, 
relief was sought by treating the cisterns and the sewer. Some relief 
followed, but it was discovered that the mosquito supply came from 
another source. Each negro hut scattered over the country has a 
rain barrel or a water tub at one or two corners, and here the mos- 
guitoes bred undisturbed through the greater part of the season, the 
prevailing south wind carrying them for over a mile. 
The only mosquitoes at College Station are species of Culex, no 
Stegomyia having been found. A few specimens of Anopheles, blown 
in by a mild east wind from a pond in the valley of Carter Creek, 
were taken during July. This is the only breeding ground of Ano- 
‘pheles close to College Station, but the supply is blown northward by 
the prevailing winds. Although mosquitoes breed there all winter 
and maintain a high percentage of malaria cases in the neighborhood 
during the summer, they do not affect the college, since nearly all 
winds from that direction are “ northers,”’ which rarely carry mos- 
Guitoes. The only other breeding place of Anopheles of any imnport- 
ance is 17 miles southwest across the Brazos River. Although the mos- 
auitoes keep malaria alive in that locality they do not affect the college. 
The few cases of malaria that appeared at College Station originated 
in other localities, and such cases were not a menace to the community, 
as there was no agency for carrying the disease.
