450 ANIMAL INTELLIGENCE. 



neously shown in the following case. It is communicated 

 to me by a correspondent, Mr. A. H. Browning. This 

 gentleman was looking at a litter of young pigs in their 

 sty, and when he went away the door of the sty was in- 

 advertently left unfastened. The pigs all escaped into 

 his garden. My correspondent then proceeds : 



My attention was called to my dog appealing in a great 

 state of excitement, not barking (he seldom barks), but whining 

 and performing all sorts of antics (in a human subject I should 

 have said 'gesticulating'). The herdm en and myself returned to 

 the sty ; we caught but one pig, and put him back ; no sooner 

 had we done so than the dog ran after each pig in succession, 

 brought him back to the sty by the ear, and then went after 

 another, until the whole number were again housed. 



In Lord Brougham's 'Dialogues on Instinct' (iii.) 

 there is narrated the story told to the author by Lord 

 Truro of a dog that used to worry sheep at night. The 

 animal quietly submitted to be tied up in the evening, 

 but when everybody was asleep he used to slip his collar, 

 worry the sheep, and, returning before dawn, again get 

 into his collar to avoid suspicion. I allude to this re- 

 markable display of sagacity because I am myself able 

 fully to corroborate it by precisely similar cases. A friend 

 of mine (the late Mr. Sutherland Murray) had a dog 

 which was always kept tied up at night, but nevertheless 

 the neighbouring farmers complained of having detected 

 him as the culprit when watching to find what dog it was 

 that committed nightly slaughter among their sheep. My 

 friend, therefore, set a watch upon his dog, and found 

 that when all was still he slipped his collar, and after 

 being absent for some hours, returned and slipped his 

 head in again. 



A precisely similar case is given further back, and 

 others are communicated to me by two correspondents 

 (Mr. Goodbehere, of Birmingham, and Mr. Richard Wil- 

 liams, of Buffalo). The latter says : 



And here let me ask if you are aware of the cunning and 

 sagacity of these sheep-killing dogs, that they never kill sheep 

 on the farm to which they belong, or in the immediate vicinity, 

 but often go miles away ; that they always return before day-
