CONTAGIOUS AND EPIZOOTIC DISEASES. "?7 



followed ini five to seven days by dullness, languor, drooping 

 •head till the nose teaches the ground, arched back, hind legs 

 advanced under' the belly and bent at the fetlocks, cough more 

 or less frequent, muscular trembling about the flanks, jerking 

 'of theneck mtiscles, heat of horns, ears, and general surface 

 (limbs cold — in fexceptional cases), and impaired appetite and 

 rumination. Soon weakness compels lying down, by choice in 

 witer, eyes are glassy and fixed, secretions lessened, dung hard 

 and coated with mucus, Or with clots of blood, and the urine 

 changes to a deep red or black and coagulates ah boiling. The 

 mucous membranes are of a deep yellow or brown, that of tke 

 rectum seen in passing dung is of a dark red, as in Rinderpest. 



All these symptoms become aggravated, weakness becomes 

 extreme, and the patient dies in a state of stupor, or sometimes 

 in convulsions-. ' ■ . . . . .■ ■ . r ;; 



The disease usually passes unhotited in the' Texan cattle, 

 but is exceedingly fatal in northern beasts. ■ ' ■' 



Contagion takes place through ' the bowel discharges, and 

 Toads, pastures, water-courses, etc.; beconve efficient bearers 'of 

 the virus. It is destroyed at once by frost, and has never been 

 satisfactorily demonstrated to be conveyed from one northern 

 animal to another. Sucking calves rarely suffer. One attack 

 does not protect against another. ' ='' •'■•' 



Fnvmiion.-^lt should be enforced by United States law that 

 no Gulf-coast cattle should be moved north excepting after the 

 first frosts of autumn, or before the last frosts of spnng. Theh 

 would the traffic be safe for all the North. The time would 

 vary for the different States, but the ea'rfier or later traffic' for 

 the extreme north should -Tje by direct route without inter- 

 mediate unloading • A general restriction of this sort, with tlife 

 expense levied on all the States, would be more economical and 

 satisfactory than a supervision by each State of its own frontier 



Treatment should never be called for. It may, however, be 

 resorted to with less danger than in the case of a true •l:)lagU«.
