Colour Discrimination in Dog ; Dog separating Combatants. — 

 A Russian Sable Pomeranian will not go near anything red, and 

 has a decided preference for pale blue. Repeatedly rags of each 

 colour have been given him to play with, and he has never been 

 known to touch a red one, while the blue or green have been 

 ripped to pieces in a very short space of time. A Retriever was 

 nicknamed the "Policeman " because he would always separate two 

 other Dogs who were fighting, or those which looked as if they 

 might. He would always tackle the aggressor, and not leave him 

 until the dog attacked was safely away. — (Miss) R. Holloway. 



Vegetarian Appetite in Cat. — It was never safe to leave a 

 Persian cat near cucumbers. He has often eaten one in the night. 

 Besides this, he has a distinct love for peas, beans, grapes, figs, 

 dates, and potato-parings. — (Miss) R. Holloway.

Singular Nest of Willow- Wren. — This morning, August 4th, 1915, 

 I noticed a small bird fly into a Crimson Rambler rose on the old wall 

 which divides my garden from a neighbour's. I sent my gardener 

 for a ladder, and found, at a height of about eight feet from the 

 ground, the nest of a Willow-Wren, with young birds just ready to 

 fly. Two or three of them, which we disturbed, are now about the 

 lawn, giving their parents much anxiety ; the rest are still being fed in 

 the nest, which is so overweighted as to look almost like a Sparrow's 

 nest with poultry feathers hanging out. No doubt there are records 

 of this species breeding late, and placing the nest high above the 

 ground ; but the combination, I imagine, must be unique. —

Notes on the Laying of the Cuckoo and the Removal of Eggs 

 of Foster-Parent. — Although so much has been written of the life- 

 history of the Cuckoo, there still appear to be many queries that 

 require additional observations recording, and it would be of interest 

 if those who have information at first-hand would give their personal 

 experiences. The Cuckoo evidently does not wait until a full clutch 

 is laid by the foster-parent, but places its egg in the nest when one 

 or more eggs have been laid. I have never known an instance, 

 however, of its eggs being placed in the nest before an egg had been
