48 Bulletin 827, U. S. Dept of Agriculture. 
quarantine and the States of Louisiana, Alabama, Georgia, Arkansas, 
and Texas have compulsory State-wide dipping laws in effect. It 
is expected that the Texas-fever tick will be entirely banished from 
this region by 1923. Cattlemen contemplating the purchase or lease 
of lands should be familiar with prevailing conditions. Many 
local areas and counties are being released from quarantine from 
time to time and anyone contemplating the movement of cattle into 
the Piney Woods region should write to the Chief of the Bureau of 
Animal Industry, Department of Agriculture, Washington. D. C, 
for the latest regulations defining the territory. 
Mosquitoes and flies, which are often given as a serious objection 
to cattle raising, are not of any considerable economic importance in 
the Piney Woods region. 
Screw worms are prevalent in the western portion of the region, 
but the damage is avoided by dehorning and castrating animals in 
cool weather, when the flies are not active. 
Anthrax or charbon is not prevalent, although it is known to occur. 
Regions which are low and swampy are much more subject to this 
disease than the dry, sandy pine lands. The disease may be pre- 
vented by vaccination. 
Blackleg occurs, but is no more prevalent than in other sections of 
the country. As a precaution young cattle should be vaccinated 
each year. 
Tuberculosis is a disease practically unknown among the native 
cattle. This is no doubt due to the hardiness of the animals and the 
lack of close housing. With the eradication of the cattle tick there is 
no disease or pest that can be termed an economic barrier to beef- 
cattle production. Although the common diseases to which cattle are 
subject are present they are no more prevalent than in other regions, 
and the native cattle are subject to tuberculosis in a markedly less 
degree than northern cattle. 
In purchasing northern cattle for breeding purposes extreme care 
should be taken not to introduce tuberculosis into the herd. Regu- 
lations require the testing of cattle for interstate shipment, and cattle 
should be purchased subject to retest. 
WATER SUPPLY. 
Next to abundant pasture an abundant supply of water is an indis- 
pensable feature of desirable cattle range. Water must be had at 
any cost, and where the supply is not dependable from year to year 
the cost of deep wells is well-nigh prohibitive for the man with a 
small number of cattle. 
The natural water supply of the Piney Woods region is very 
abundant. The heavy rainfall supplies many springs, which furnish
