were dead. Upon visiting tlie various tanks I found that four of tliem 

 contained the mosquito larva' in very large nuuibers, as I had expected 

 to tind. The otlier tanks, with one exception, are within closed build- 

 ings in whit'h 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 j)laced a cup of kerosene in the tank every Monday 

 morning. June 2(), 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- 

 l)lished 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 tlie 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 kerosene 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. 



The report of the committee on nominations was presented by the 

 chairman, Mr. Lintner, as follows :

Mr. Smith moved that the usual custom be followed as to the time
