CONSEBVATION AND TEE VETEBINABIAm 



As civilization advances and freer com- 

 merce develops with other nations, new 

 conditions arise. New dangers menace our 

 plant as well as our animal food supply. As 

 farmers must now contend with the San 

 Jose scale and other insect pests which 

 formerly caiised no concern but now 

 threaten his fruit and other crops, so must 

 the veterinarian realize that new dangers 

 in the form of foreign diseases as rinder- 

 pest, foot and mouth disease, trypanosomes 

 and possibly others may at any time invade 

 our territory. Aside from the possibility 

 of the danger of this foreign invasion, the 

 diseases already established here in the 

 form of glanders, anthrax, tuberculosis, 

 abortion and sterility are sufficient cause 

 for the most serious apprehension. The 

 condition may soon arrive, if it has not 

 already arrived, when, in certain sections, 

 it will be difficult to maintain the normal 

 size of the herds, letting alone the question 

 of surplus stock for the market, because of 

 the ravages of bovine diseases. If there is or 

 should be difficulty in maintaining the size 

 of the herds as they now are, the problem 

 of rearing surplus animals is indeed a 

 serious one. 



The old order changeth. The day when 

 the only desirable practise was in the city, 

 and this was concerned principally with 

 the horse, has gone by. While the automo- 

 bile has undoubtedly affected city practise, 

 it is no more likely to supplant the horse
