Worcester, however, states that it is said by relial)le people 

 that nearly one-tenth is affected. Quite a number state 

 that they have never known of a case in their vicinity, while 

 others believe it to exist but are unable to state to what 

 extent. Some correspondents state that such cattle are 

 becoming more common than formerly. A correspondent 

 in central Franklin states that the disease is almost unknown 

 in that ofjcn country. A correspondent in Essex states 

 that ver}^ little is said of this disease in swine ; that he kills 

 nearly all the hogs in his town, and finds very many of them 

 affected with tuberculosis in all stages of the disease, and 

 that it grows more common every year. He thinks it safe 

 to say that twenty-five per cent of all the hogs he has killed 

 the .past season were more or less affected with tuberculosis. 

 The sixth question asked was, Does (his disease ajjpeai' to 

 be more common in any 2Jorticular breed of cattle, and under 

 what system of care and feeding do you consider it most com- 

 mon? A large number of the correspondents did not answer 

 this question for the reason that they did not feel competent 

 to do so intelligently. There was insufficient evidence offered 

 to warrant the statement that the disease is confined to any 

 particular breed of cattle. It is found more or less in all 

 cattle, from the cow to the working ox. A correspondent 

 in western Hampshire says it is often aggravated by 

 exposure to inclement weather and diet of musty and 

 unwholesome food. Another in central Hampshire says 

 high feeding with concentrated feed and tight, warm barns 

 tend to breed the disease. Another in central Worcester 

 says, under the old systen of cold barns and low feedins:. 

 Anot^her in northern Worcester saj's high feed and tight 

 stables and crossing with a feeble breed. Another in central 

 Worcester says he thinks excessive high feeding with want 

 of suitable ventilation is likely to develop the disease. One 

 in southern Middlesex says that cows that are deep milkers 

 seem to be more liable to the disease than poor milkers 

 or dry stock. Another in northern Middlesex says profuse 

 feeding and grain to stimulate the production of milk is evi- 

 dently a cause of the disease. A correspondent in central 

 Franklin says close confinement and filth. Another in 

 eastern Hampden says the weaker the natural system the
