This bulletin is prepared and sent to the farmers of Colorado 
in the hope that they will profit by the experience of San Luis Val¬ 
ley and control hog cholera before it has become widely dissemin¬ 
ated over the state and its control becomes apparently a hopeless 
task. 
HOW THE DISEASE IS SPREAD. 
Regardless of breed or condition of hogs, they cannot con¬ 
tract hog cholera unless the virus of this one disease is carried to 
them, any more than you can have a crop of wheat without sowing 
the seed. Self-interest actuates the average farmer to save his own 
hogs regardless of his neighbor. From the standpoint of the sani¬ 
tarian who is seeking to eradicate hog cholera the most important 
thing is to prevent the carrying of the virus from infected premises. 
The following are a few suggestions as to ways the disease is 
spread: 
1. By leaving dead hogs in the fields and ditches or by the 
roadside. Buzzards, magpies, *pigeons, s ^ ra y dogs and other ani¬ 
mals that carry the infection should be looked after. There is a 
state law which requires that dead animals shall be burned or buried 
immediately. Burning is preferable, but where there is not suffi¬ 
cient fuel to burn them, such as in the plains district, they should be 
covered with lime and buried six feet deep. 
2. By persons carrying the infection on their feet. It should 
be remembered that the pig pens are impregnated with the infecting 
material from the discharges of diseased hogs and the owners of 
healthy hogs should not go, nor allow the hired help to go, on prem¬ 
ises where there are sick hogs. 
3. By hogs having access to ditches and creeks where there 
are diseased hogs upstream. In this case it will be better to remove 
them at once and supply them with water from a well. 
4. By shipping in stock hogs; trailing them along the public 
roads and failing to observe the state law, which requires that hogs 
moved from one part of the state to another, or from one farm to 
another, shall be held eighteen days in quarantine before being 
mixed with other hogs. This law will work some inconvenience to 
farmers who have been in the habit of exchanging stock hogs, but
