pose—to save the hogs and to cut short the disease, thereby mini- 
mizing the chances of its spreading. We have seen that the second 
object was not attained to any appreciable degree. The effect of the 
work upon the actual losses of hogs from disease is a subject that 
requires more extended consideration.

Table 2 gives in condensed form a record of losses from cholera 
in each of the 14 experimental counties for the years 1912 to 1915, 
inclusive. The table also shows the date upon which work was 
begun in each county. It is important to keep this date in mind in 
studying the table to determine the effect of the work upon the 
course of the disease, for as the work began 12 months earlier in 
some counties than in others the effects naturally became apparent 
in different years. The figures given are not merely estimates, but, 
on the contrary, were obtained by a personal canvass of the coun-
