Cattle Imports Through Canada. 71

 Canada, they shall not be admitted to duty under any 

 conditions unless you shall be satisfied, first, that they 

 were not imported into Canada from England, directly or 

 indirectly ; or second, that if imported into Canada from 

 England, directly or indirectly, they did not arrive in

 at your port. In no case shall such cattle from Canada 

 be admitted if you have reason to suspect that they are

 we should exclude all cattle that had within three 

 months come in contact with English cattle imported 

 within six months of the arrival of such Canadian cattle 

 at an United States port. Here we must allow for two 

 successive incubations of three months each in the En- 

 glish and Canadian cattle respectively. 



It is further deficient in not imposing a similar prohi- 

 bition on the cattle imported from the other infected 

 countries of Europe, and stock that have come in con- 

 tact with these. At present we have the anomaly of 

 United States importers of Dutch cattle having to sub- 

 mit them to a quarantine of ninety days, while the Cana- 

 dian importer may introduce the same animals and ship 

 them to us at once, free from all restrictions. Here the
