The charges were placed at night after the workmen had left, but 
one room above was not fumigated. The next morning, after airing 
the building for a couple of hours, the insects were brushed up and 
destroyed. Quite a number of these insects were found on the

up and destroyed. 
Mr. Sanderson had found such fumigation for fleas effective, even 
under circumstances where eggs must have been present. 
Mr. Titus reported, however, that he had known instances where 
even two or three trials had failed to eradicate fleas.

Experiment Stations (1903), United States Department of Agricul-
