The next item I will take up is on pa<;e OiJ, " For all neces.sary 

 expenses for scientilic investijrations in disea.ses of animals.'' This 

 item covers all the investijjfational work we are doin<^ on animal 

 diseases, investigations of tuherculin. serums, antitoxins, and other 

 products, and renuiins the same as for the current year. This is 

 the item under which we are also conductin<r the work on conta- 

 <rious abortion.

 ta«i:ious abortion t 



Doctor Moiiij^:r. Yes, sir; that is the item which is referred to

Mr. liucHAXAN. How are abortions contaj^ious? 



CONTAGlOrS ARORTION OF ANIMALS. 



Doctor MoHUJi. There is a <rerm that is the cause of conta<(ious 

 abortion. You can isolate klmt ^erm from the afterbirth of a cow 

 and ^row it on media and feed it to other cows that are i)re<rnant, 

 and they will al)ort in four or five months' time. The same disease 

 has now been found to affect pijrs. There has been more swine 

 abortion in the last six or ei<rht months than we have ever known 

 before. The same «r<^rm that affects cattle has been found in swine, 

 producinfr the same results, and we are now doin<r considerable work 

 on swine abortion. We find that the living abortion vaccine that 

 we have been workinnf on for the last two yeare in seven or ei^ht 

 herds is produ<'in<r better results than any other method of treatment. 

 We are also usin<; various methods for the management of the herd 

 in ^ettin^ rid of the infectious material from aboitin<r cows. We 

 now pay less attention to the bull as a carrier, and we are <rPttin<: 

 very satisfactory results with the combined method of herd manajre- 

 ment and livintr abortion vaccination. 



Mr. Andersox. At the dairy show my attention was directed to 

 a supposed abortion cure invented by'^a man whose name I do not 

 recall. 



Doctor MoHLER. There have been a number of cures advertised 

 for abortion. One man in Wisconsin used to j^et a dollar for an
