of these escaped by flying away from the house. Two mosquitoes were captured 
on strands of cobweb. One was taken while resting on brick support. The 
remainder were collected from surface of wood, usually near a moist place. 
Inspected Eastland estate, 2 miles north of Scott. Under the manager’s 
residence the entire flooring was inspected. In this particular locality in Sep¬ 
tember, 1914, Mr. Le Prince had counted as many as 30 Anopheles to the meter. 
Two chimney supports under the house were likewise inspected, but no 
mosquitoes were found. The several outhouses, horse shed, and hay loft yielded 
nothing. Four hollow trees were examined; two were subjected to sulphur 
dioxide fumigation. This was done by spreading white paper over the ground 
inside of the tree; bricks were placed on this supporting an iron pot contain¬ 
ing sulphur and alcohol. Stiff paper, held in place by boards, effectively 
covered the opening. The hollow in these trees extended fully 15 feet, so that 
it was necessary to apply the sulphur fumes for a long period. After several 
hours the pot was withdrawn and paper and interior of tree were inspected, 
but no mosquitoes were found. The only living things seen were six small, 
stupified flies, collected from the layer of paper. 
February 10 .—Inspected a large number of houses on Belmont plantation. 
Several Anopheles were taken in the bright light under the plantation man¬ 
ager’s house; most of these were seen on the flooring near the walls. 
The first general mosquito infestation was noticed on February 11, 
beginning at 4.30 p. m., in the woods of Mound plantation. Here, 
while making an inspection trip with three other horsemen, Anophe- 
les were observed biting our horses, particularly on the sides exposed 
to direct sunlight. It was noted that the flight was from northeast; 
that there was a moderate breeze from the southwest; and that the 
nearest settlement, comprising 45 dwellings, lay approximately three- 
eighths of a mile to the west, the direction apparently selected by the 
voracious mosquitoes. 
Large numbers of mosquitoes were observed to be coming from 
the general direction of the depth of the woods, where the company’s 
main drainage ditch was located. Prior to this time, and subsequently, 
at least once weekly for a period of three months, this body of water 
was scrupulously explored for any young forms of Anopheles. Im¬ 
mediately following the general infestation, a special and conscien¬ 
tious effort was made to locate empty puparia, to account for the 
emergence of such a swarm of mosquitoes. Absence of these or other 
young forms was invariably the rule. 
On the following day, February 13, mosquitoes were still present 
in considerable numbers, but few were found a month thereafter. In 
fact, a relatively warm day was required to induce biting, although 
horses were used to bait the mosquitoes. Between March 6-13, only 
14 Anopheles were collected from two plantations, but the two follow¬ 
ing days proved to be warmer, when 69 specimens were collected from 
a horse used for the purpose. Biting the horse did not begin usually 
until nearly 3 p. m. upon these and several other occasions. The 
mosquitoes were seen to come from the direction of the near-by
