were dead. Upon visiting the various tanks I found that four of them 
contained the mosquito larvae in very large numbers, as I had expected 
to find. The other tanks, with one exception, are within closed build- 
ings in which the mosquitoes are not apt to breed, as they are situated 
in dark garrets and used for fire protection. The exception noted was 
a tank used for general household purposes, and the gentleman owning 
it assured me that he placed a cup of kerosene in the tank every Monday 
morning. June 26. I placed in each tank a gallon of kerosene with the 
result that ten days later the mosquitoes had almost entirely disap- 
peared from the campus, and we were able to sleep without mosquito 
bars. The amount of kerosene used was much more than would have 
been necessary, and I am sure the same work would have been accom- 
plished had only five of the tanks been treated, these being the only 
ones that are outdoors and not protected much. All the outdoor tanks 
are covered, but there are many cracks where the mosquitoes can get in 
and out. An examination of the tanks has been made about once a 
week since the kerosene was put on, and on July 18 more kerosene was 
put in two of the tanks. Upon all the outdoor tanks a thin film of ker- 
osene has remained since the kerosene was put in. The campus is now 
nearly free from mosquitoes and has been so since ten days after the 
kerosene treatment. Hereafter during the summer kerosene will be 
put in the outdoor tanks, putting in enough to keep a thin film over the 
top of the water. 
I have also found that kerossne is also a good article to use to pre- 
vent mosquitoes from annoying one when the mosquitoes are numerous. 
To use it for this purpose a little is smeared on the back of the hands 
and also upon the face. At first thought this would seem to be a disa- 
greeable operation, but a trial of it will prove that it is not disagreeable 
in the least. It is quite effective in keeping the mosquitoes away and 
is much better than the Florida method, which I have been told is to 
remain secreted under a large iron kettle and with a hammer clinch the 
bills of the mosquitoes as they are thrust through the kettle.
