This is an inexpensive type of cattle barn which has a large storage space for loose hay. Working plans for constructing the barn may be obtained on application. DISEASES AND PESTS. The cattle tick {Margaropus ammlatus), which is the carrier of the disease known as Texas or splenetic fever, is the only pest that has been a real detriment to the development of the cattle industry. Fig. 12.—Modern cattle barn on the experiment farm at Collins, Miss. With the exception of the roof this barn was constructed of used lumber from abandoned " dummy-line" trestles and mill timbers. Note the storage room above and the daylight underneath. of the Piney Woods region. The native cattle become immune from the disease through contracting it in a mild form as calves, but ma- ture animals brought in from Northern States or tick-free terri- tory are very susceptible. The disease appears in from 13 to 90 days after exposure and is fatal in 90 per cent of the cases in mature susceptible cattle. The damage done consists of the loss of ani- mals from the fever, the extra feed needed to support the blood- sucking parasites, the penalty placed on quarantined cattle at the markets, and the prevention of the bringing in of pure-bred ani- mals for improvement of the herd. The total damage has been beyond reasonable estimate. In 1906 the Federal Government and State and local authorities began the systematic eradication of the tick and great progress has been made in recent years. The entire States of Mississippi and South Carolina are now released from. Please note that these images are
