Dogs with Foreign Armies 167 



The attendant and his assistant must remain a1 opposite 

 ends of the route. Where this is not the case, and one ol the 

 attendants is forced to leave his post, owing to patrols, 

 for example, it is still possible to use the messengei I 

 but its work in such cases is essentially unreliable, as il 

 obliged to pick up and follow the man's trail by smell. 

 This, as a rule, is rendered very difficult owing to man) 

 external influences. In such a case, moreover, the d 

 would have to be specially trained in tracking." 



I here interrupt the report to point out that the sy • 

 of training here advocated, is that of the liaison, or the 

 two-keeper method. I have elsewhere discussed the ad- 

 vantages and the disadvantages of this system, as against 

 the one-way-return-to-keeper method. Of course, mi] 

 depends on the rapidity of output demanded. Germany 

 had such large quantities of dogs, fully trained and ready 

 to put into the field, at the outbreak of war, that thi 

 was not the same urgency placed cm the training staff, and 

 they could pursue the slower' form of training ; but, as 

 I have already said, there are, apart from rapidity of output, 

 several other distinct advantages to be obtained by special- 

 izing, certainly for the greater number of messenger d 

 in the one route method.
