16 BOARD OF ACRICULTURE. 



The kidiiovs arc congested, and the mucous membrane within 

 them often blood-stained. In a small percentage of cases tho 

 bladder contains clear urine ; in the great majority tins orgau 

 is greatly distended by bloody urine, and its internal lining is 

 dotted \vitb small, bright j)in-point-like extravasations. 



From the evidence already obtained, the following deductions 

 are made : — 



That Texas cattle, when driven or transported North in the 

 spring or summer months, communicate a fiital disease to native 

 cattle, although the Texas cattle appear perfectly healthy. 



Tiiat Texas cattle are not subject to the same disease in Texas. 



That it is necessary, with exceptional cases, that native cattle 

 feed on the same land where Texas cattle have grazed, to become 

 infected. 



That aged animals are more susceptible to the disease than 

 young ones. Suckling calves rarely die from it. 



That native cattle do not communicate the disease to others. 



That Texas cattle, after having been wintered North, will not 

 communicate the disease. 



That severe frosts remove the danger of communicatin2; the 

 disease, and that Texas cattle may be safely brought North 

 from November to March. 



That it is of great importance, both to the Eastern and "West- 

 ern people, that the tralVic iu Texas cattle be unrestricted as far 

 as it can be done with safety. Through it the Western farmer 

 is enabled to turn his rich fields of grass and corn into money, 

 and the Eastern people are furnished with a supply of beef at a 

 price within the means of every one. 



TREATMENT AFTER SYMPTOMS. 



As but little is known about the disease, but little can be said 

 of treating it. In the Western States the turning of a herd of 

 sick cattle into a lield of green corn has proved beneficial ; con- 

 sequently, when practicable, cathartics should be administered. 



In Chicago seventeen animals were treated with quinine and 

 aromatic suljihurie acid, nine of which recovered. In New 

 York carbolic acid has been administered, and highly extolled. 

 In rinciiuuiti several animals were treated with the same 

 remedy, without apparent benefit.
