tuberculosis, is not deserving of public confidence. Any one can 

 purchase tuberculin from some of the leading druggists and also 

 the necessary instruments with which to administer it, but we 

 would advise the avei'age farmer and stock owner not to undertake 

 a test of this importance, the complete success of which depends 

 upon experience and professional skill. In would be better to 

 employ a competent veterinary surgeon. The expense ought not 

 to be very great. For the present, as far as other work will per- 

 mit, the Experiment Station will undertake to examine cattle for 

 tuberculosis in any part of the State where the owner |will pay 

 travelling expenses. We cannot promise to continue to do this 

 indefinitely, but for the next few months, for the purpose of 

 obtaining data relative to the prevalence of tuberculosis among our 

 cattle, we hope to be able to answer all calls in this direction. It 

 is possible that arrangements can be made to examine a limited 

 number of large herds free of all expense to the owner. After a 

 herd is once free from tuberculosis, we can only be sure of keeping 

 it free by attention to the following details : 



1st. Have the barn thoroughly disinfected. 2nd. Retest the 

 herd at intervals. 3rd. Test all purchased animals before adding 

 them to the herd. 



GLANDERS. 



This is a disease prevailing among horses and mules, and trans- 

 mitted from them to some other domestic animals and to man. 

 Cattle are not subject to it. In a very general way it bears some 

 resemblance to tuberculosis. Its presence has often been difficult 

 and even impossible to determine. Horses are sometimes affected 

 with it for years, and carry the disease to other horses without 

 manifesting any symptoms that lay them open to suspicion. The 

 disease is conveyed to man and other animals brought into con- 

 tact with the diseased one chiefly through the nasal discharges and 

 from ulcerating lymphatic glands. Recoveries from glanders are 

 probably less frequent than from tuberculosis, and when trans- 

 mitted to human beings it usually assumes an acute and speedily 

 fatal form. The glanders bacillus is the active source of this 

 disease and this bacillus is given off from diseased animals, chiefly 

 in the nasal discharge and in the discharge from the ulcerated 

 lympathic glands "Well animals contract the disease by introduc- 

 ing into their systems in some way the glanders bacilli contained
