1040 THE LOG. 



Aosta. Two more make the voyage on the Swiss side, toward 

 Martigny to a distance of about nine miles from the Hospice. They 

 all go just to the last cabins of refuge that have been constructed 

 for the benefit of travelers. Even when the snow has fallen, during 

 the night, the dogs find their way surely and correctly, and do not 

 deviate from the beaten way a yard. The marks of their feet 

 leave a track 1 which is easy for the travelers to follow as far as the 

 Hospice. Two dogs are made to go over the same road together, 

 so if one perishes it is replaced by another, — a young one, who is 

 instructed and trained by the survey dog, of which he is the pupil. 

 When the dogs arrive at the cabins of refuge, they enter them to see 

 if there are any travelers seeking shelter there, in which case they 

 entice them to follow. If they find any travelers who have suc- 

 cumbed to the cold, the dogs try to revive them by imparting 

 warmth in licking their hands and face, which not seldom produces 

 the desired effect. If these means are inefficient, they return in all 

 speed to the Hospice, where they know how to make themselves 

 understood. . . . The monks immediately set out, well provided 

 with means of recovery."
