Tuberculosis. 147 



work — literary, scientific, manufacturing, commercial, domestic 

 and manual of the great host of consumptives waiting all over the 

 land to fill the places of this fatal eighth in coming mortality 

 statistics ; for the losses represented by the bills of the physician, 

 nurse and druggist for these invalids ; and for the losses repres- 

 ented by the many migrations and exiles in search of health and 

 of the costly consumption hospitals and sanitaria ? And who is 

 to pay in the future for the needless harvest of similar fruits, 

 which the seeds now sown through our supineness, must inevitably 

 produce in the coming generations ? 



Is it not a truer economy to destroy the seed before in has ger- 

 minated, or even before it has been sown, than to wait for the mul- 

 titudinous evils that must attend on its growth and fructification ? 



Preventive Measures for Adoption by the Stockowner. 



If he will the stockowner can extirpate this disease from his 

 herd and thereafter keep the herd pure from such contamination. 

 The following are the main precautions necessary to tnis end : 



I St. Board up the partitions of the stalls at the front so that 

 no two cows can feed from the same manger nor lick each other. 



2d. Keep each animal strictly by its own stall and manger. 



3d. When any animal is suspected don't let it use a drinking 

 trough nor bucket in common with other animals. 



4th. Avoid old milch cows and unthrifty ones, or keep them 

 secluded from the rest of the herd. 



5th. The following conformation usually indicates a weakness 

 of constitution and a susceptibility to tuberculosis : Head narrow 

 between the horns, sunken eyes, depth of cavity (temporal) back 

 of the eyes, thin narrow ewe neck, chest small, lacking in both 

 breadth and depth, hollow flank and tendency to pot belly, a 

 general lack of muscle so that the limbs seem loosely attached to 

 the body, in breeds that show a variety of colors, animals of the 

 lighter shades of brown and yellow. If, however, such animals 

 are of high value for the dairy, and can be kept free from infec- 

 tion they need not be rejected. The finest conformations of 

 shorthorns, Devons, Holsteins, black or red polled furnish no 

 protection in the presence of the germ.
