presence of hibernating mosquitoes in this seemingly favorable environment, 
but all search was fruitless, although IT harborages of this nature were care¬ 
fully scanned. In many of the cut trees the roots were submerged in a natural 
basin of water, suppyling moisture to about one-third the length of the interior 
of the hollow stump. In other stumps, decomposing in the interior, the tops 
were found to be open so that the interior of the tree stump formed a natural tube 
to which the rain had access. In still others, which were hollow to a consider¬ 
able distance, they were entirely protected from the rain and moistened only from 
rain-soaked soil at the roots. Many stumps, seemingly sound externally with 
solid bark, were rotted in the interior, and had numerous channels made by 
burrowing insects, and holes made by owls, woodpeckers, and rabbits, thus 
seeming to furnish conditions attractive to resting mosquitoes. In many of 
these the entire bark was cautiously stripped to expose the interior, when the 
holes and air spaces were minutely inspected. Other trees were carefully in¬ 
spected for mosquito infestation; some old trees with hollows exposed to the 
wind found isolated in cotton and corn fields, as well as trees and stumps in_ 
the interior and on the edges of the swamp; also the tree stumps and trees in 
the heart of the dry woods. The hollows of some of these trees extended into 
the roots, the spaces of which were prodded with sticks. Also 22 fallen trees 
had their bark removed, and the surrounding accumulation of leaves and wood 
pulp were well scrutinized. No mosquitoes were seen in these natural environ¬ 
ments, though they were apparently suitable resting places, and indeed, in sev¬ 
eral of the places inspected, mosquitoes had been found previously during the 
time of mosquito activity. 
February 8 .—It was noted that as late as 7.30 a. m.- there was a coating of 
one-eighth to one-fourth inch of ice in the road side ditches. 
Inspected the environs of a large frame building, fitted up as a general store 
and post office. The interior, which was dark in the early morning, was seen 
by the aid of an electric flash light and an oil lantern. Here numerous situa¬ 
tions, ordinarily favorable to mosquitoes, were encountered. The building was 
unusually dark at all times, the only sources of light being obstructed by broken 
shutters fastened securely. The ordinary accumulation of empty barrels and 
boxes glutted the available storage space. Several of these were superimposed, 
so that the lower as well as the upper one was accessible to mosquitoes. 
Empty sacks in the corners and loose boards leaning against the wall, as well 
as a large empty piano packing case, were inspected. The vacant spaces, on 
36 feet lengths of shelving and under the numerous counters, were examined 
carefully, with negative results. An adjoining wreck of an abandoned bam, 
once utilized as a blacksmith shop, but now inhabited by a family of swine, was 
given careful consideration, with no better results. 
Following this the interiors of nine negro cabins were examined. All of the 
inhabitants agreed that mosquitoes were not found in their houses during the 
cold season. These persons were offered 25 cents for each mosquito found 
during our visit and subsequently, but without return. We inspected the 
cracks in these log houses, under shelving, under loose wall paper, the wooden 
ceiling, and sacking suspended therefrom, also furniture, beds, and loose boxes 
littered about the floors. The inspection included the underside of these 
houses. No mosquitoes were found. 
February 9 .—Ice about 8 a. m., melted by 9 a. in., warm at noon—about 
14.5° C. to 15.5° C. in shade. 
Caught the first mosquito since arrival. Several (9) captured in short 
time under the house of Dr. M. at 2 to 2.35 p. m. Captured six on north side 
of house, some flying away at our approach and settling again near by; two
