408 SWINE IN AMERICA 



has frequently been spread in this manner, as has been 

 strikingly demonstrated by the Indiana station in the bul- 

 letin already quoted. The loss from cholera in the state 

 of Indiana for the year ending June 30, 1897, was re- 

 ported as practically 900.000 head. The Indiana station 

 made an analysis of the figures for the years 1882- 1897, 

 showing- the losses for each township in the state, which 

 quite fully demonstrated that cholera was spread by the 

 streams. It was found that "the territory involved makes 

 three long narrow strips in the state at distances suffi- 

 ciently removed from each other, so that only a positive 

 factor could show the marked differences that exist." 

 These strips were on the Wabash and the north and south 

 forks of the White river. The losses in the townships 

 bordering on the rivers were found to be t^t^ per cent to 

 112 per cent greater than in the townships of the second 

 tier from the river, and from 83 per cent to 208 per cent 

 greater than in those of the third tier. A significant fact 

 gleaned from investigations made in 1895 and 1896 by 

 the station was that nearly everyone of the breeders of 

 pure-bred swnne whose herds escaped cholera were users 

 of well water, and that one of the surest means of 

 preventing the distribution of hog cholera is the use of 

 deep-well water. 



The Indiana station has made a number of investiga- 

 tions into the losses of swine arising from access to a 

 water supply of unhealthful or otherwise improper char- 

 acter, and the conclusion reached from these was that 

 such losses are greater by far than those which come 

 through an insufficient supply of water. Bulletin No. 70,
