was found with one opening, about 6 by 2 feet, partially protected by a torn 
screen about 5 feet from the ground, one entry door, always closed when not 
in use. Ice house contained cotton sacks, boards leaning against the wall, and 
empty boxes and barrels. The harness room was well constructed (size 4 by 6 
by 10 feet), wind proof, but would admit mosquitoes at all times. We examined 
the stable, containing cotton sacks, boards, exposed shingle roof, cornstalks 
used as bedding for stock, underside of feed trough in mangers, high and low 
rafters, and ceiling of shingles above them. 
One old abandoned barn east of Dr. M’s house contained a flat-bottomed boat 
and wooden canoe with canvas compartments. The floor of this structure 
was covered with cornstalks about one to two inches deep; it was not used 
except for storage of unserviceable waste and such odds and ends as old stoves, 
tin cans, large and small bottles, loose wire screen, boxes, worn-out stovepipe, 
and two baby carriages. These were stacked in a disorderly heap in the corner 
of the building in a pile about 8 by 8 by 4 feet high and offered many excel¬ 
lent hiding places for mosquitoes. The flat-bottom boat had the rear seat boxed 
in for a length of 2 feet; a board of this box was torn off, so that its inside 
compartments might be carefully inspected — results negative. The canoe was 
interesting and offered excellent wind shelter for mosquitoes. We ripped open 
the canvas compartments and took a photograph of the boat. While this was 
being done, it was noted that water 6 inches in depth filled the lower end. 
The stored canoe was resting at about 30° to the horizontal, so that water col¬ 
lected at the pointed end of one of the compartments. Anopheline larv« were 
absent. 
About a quarter of a mile from the house we examined the grove of trees 
surrounded by cotton fields. We examined the interior of six large hollow 
trees—one was 4 feet wide inside — also the interior of 15 hollow logs and 22 
live trees with big vines growing on them. The trees were buttressed at the 
trunk, offering excellent wind shelter. The vines had diameters up to 2 inches 
and many hairy roots to grasp the tree’s bark and would afford an insect much 
protection. One oak tree had hollows in upper portion of roots and they were 
examined by striking matches and illuminating the interior. 
Next, examined negro cabin — back, inclosed porch with lots of stuff stored, 
including parts of wooden bed which were leaning up in a corner, and cracks 
between logs of back wall of house inside of balcony—then examined corn stor¬ 
age shed with wooden shingle roof. Results negative. 
February 6 . — Examined the premises of plantation manager, Mr. R. L. The 
residence w T as inspected within and under, and the near-by barn was likewise 
inspected. It was noted that a leafy vine, suitable for mosquito harborage, 
covered the sides and roof of the main building. Two large animal sheds with 
moss-covered roofs were examined. A small bell tower near cow barn also re¬ 
ceived attention. The inspection included a near-by cotton gin and warehouses. 
Mosquitoes were absent generally. 
February 7 . — Spent the entire day in wood and cypress and oak swamp near 
Dr. M’s estate. At the present time the swamp is being drained and the woods 
cleared. During the summer of 1914, a moderate number of Anopheles larvae 
were collected in this swamp. We inspected the contents and surroundings of 
72 cypress and oak trees and stumps with loose bark and worm-eaten interiors, 
many partly hollow and in a state of collapse. These were torn apart for more 
careful examination, as they offered numerous excellent hiding places for mos¬ 
quitoes. We found piles of leaves in some instances heaped to the trunks and 
crotches and covering fallen logs. T^iese were examined minutely. The loose 
bark on cypress stumps was observed to be so placed as to afford excellent 
shelter from rain, sun, and wind. A special effort was made to ascertain the
