if the doors opened from them. There Avas a decided difference, 

 however, in opening a door if it opened toward them. Cufty was 

 never able to do it. With Jack it was about as easily done as it 

 was by the Indian servant girl. Quickly and deftly would he 

 shove up the exposed latch and the curved part of the thumb piece 

 and draw it toward him. If the door did not easily open, the 

 claws in the other fore paw speedily and cleverly did the work. 

 The favorite resting place of these two magnificent dogs was on 

 some fur rugs on my study floor. Several times have we wit- 

 nessed the following action in Cuffy, who w'as of a much more 

 restless temperament than Jack: When she wanted to leave the 

 study she would invariably first go to the door and try it. If it 

 were in the slightest degree ajar she could easily draw it toward 

 her and thus open it. If, on the contrary, it were latched, she 

 would at once march over to Jack, and, taking him by an ear with 

 her teeth, would lead him over to the door, which he at once opened 

 for her. If reason is that power by wdiich w^e " are enabled to 

 combine means for the attainment of particular ends," I fail to 

 understand the meaning of w^ords if it were not displayed in these 

 instances. 



Both Jack and Cuffy were, as is characteristic of such dogs, 

 very fond of the water, and in our short, brilliant summers would 

 frequently disport themselves in the beautiful little lake, the shores 

 of which were close to our home. Cuffy, as a Newfoundland dog, 

 generally preferred to continue her sports in the waves some time 

 after Jack had finished his bath. As they were inseparable com- 

 panions. Jack was too loyal to retire to the house until Cuffy was 

 i-eady to accompany him. As she was sometimes whimsical and 

 dilatory, she seemed frequently to try his patience. It was, how- 

 ever, always interesting to observe his deference to her. To un- 

 derstand thoroughly what we are going to relate in proof of our 

 argument it is necessary to state that the rocky shore in front of 

 our home was at this particular place like a wedge, the thickest 

 part in front, rising up about a dozen feet or so abruptly from the 

 water. Then to the east the shore gradually sloped down into a 

 little sandy cove. When Jack had finished his bath ho always 

 swam to this sandy beach, and at once, as he shook his groat body, 

 came gamboling along the rocks, joyously barking to his companion 

 still in the waters. When Cuffy had finished her watery sports, 

 if Jack were still on the rocks, instead of swimming to the sandy 

 cove and there landing she would start directly for the place where 

 Jack was awaiting her. If it wore at a spot where she could not 

 alone struggle up, Jack, firmly bracing himself, would roach down to 

 hor and then, catching hold of the l)ack of her neck, would help her
