the alert. For some time they watelicd in vain. They eagerly 

 scanned every point of vision, and for a time could observe noth- 

 ing iinnsnal. 



" Ilnsh! " said one; "see that dog! " 



It was Csesar, cautiously skulking along the trail. He would 

 frequently stop and sniff the air. Fortunately for the Indian 

 watchers, the wind was blowing toward them, and so the dog did 

 not catch their scent. On he came, in a quiet yet swift gait, until 

 he reached the spot where Papanekis stood when he pulled in the 

 net. He gave one searching glance in every direction, and then he 

 set to work. Seizing the rope in his teeth, Caesar strongly pulled 

 upon it, while he rapidly backed up some distance on the trail. 

 Then, walking on the rope to the water's edge as it lay on the 

 ground, to keep the pressure of the current from dragging it in, 

 he again took a fresh grip upon it and repeated the process. This 

 he did until the sixty feet of rope were hauled in, and the end of 

 the net was reached to which it was attached. The net he now 

 hauled in little by little, keeping his feet firmly on it to securely 

 hold it down. As he drew it up, several varieties of inferior fish, 

 such as suckers or mullets, pike or jackfish, were at first observed. 

 To them Caesar paid no attention. He was after the delicious 

 whitefish, which dogs as well as human beings prefer to those of 

 other kinds. When he had perhaps hauled twenty feet of the net, 

 his cleverness was rewarded by the sight of a fine whitefish. Still 

 holding the net with its struggling captives securely down with his 

 feet, he began to devour this whitefish, which was so much more 

 dainty than the coarser fish generally thrown to him. Papanekis 

 and his comrade had seen enough. The mysterious culprit was de- 

 tected in the act, and so with a " Whoop! " they rushed down upon 

 him. Caught in the very act, Cassar had to submit to a thrashing 

 that ever after deterred him from again trying that cunning trick. 

 Who can read this story, which I give exactly as it occurred, 

 Avithout having to admit that here Cajsar " combined means for 

 the attainment of particular ends "? On the previous visits which 

 he made to the net the rapid current of the stream, working against 

 the greater part of it in the water, soon carried it back again into its 

 place ere Papanekis arrived later in the morning. The result was 

 that Caesar's cleverness was undetected for some time, even by these 

 most observant Indians. 



Many other equally clever instances convince me, and those 

 who with me witnessed them, of the possession, in of course a lim- 

 ited degree, of reasoning powers. Scores of my dogs never seemed 

 to reveal them, perhaps because no special opportunities were pre- 

 sented for their exhibition. They were just ordinary dogs, trained
