IO The Carntvora. 
small quantity of powdered sulphur introduced into a mess 
of soft food, and thoroughly mixed with it, will often be 
detected by a dog unaccustomed to it. This is impressed 
upon my memory by the difficulty I experienced in train- 
ing a retriever to take this most useful alterative, which 
should, I think, be given at least once a week to the extent 
of a thimbleful to every dog weighing 50lb. or more, even if 
his health be good, with half that quantity to smaller animals. 
The dog in question did not overcome his repugnance to 
the sulphur in the smallest dose for months. Salt may be 
tolerated in much larger quantities than other substances, 
though a few grains will suffice to make my retriever refuse 
his water, unless very thirsty, which indicates his conscious- 
ness of its presence. 
Veterinary authorities no doubt rightly consider that salt 
in any form whatever should never be given to the dog. I 
know one singular instance, however, of no evil result of 
frequently drinking salt water. We used to take a pointer 
to the shores of Moreton Bay, on the north-east coast of 
Australia, to work the quail and “squatter” pigeons in the 
rough grass round the salt swamps—birds in which my 
retriever, CarloI., took no professional interest at that time, 
his mind being wholly devoted to water fowl and snipe. Even 
in winter the temperature of this latitude (28deg. N.) is 
little, if any, less during the day than that of an English 
Midsummer, while that of the autumm is considerably higher. 
My diary gives records of 84deg., 90deg., and 75deg. as the 
temperature in the shade on days im May, and of 70deg. 
frequently in the months of June and July, when it may be 
considered cool. Thus, during the best shooting months the 
heat is distressing to dogs, and particularly so to pointers. 
Carlo I, having been bred in the country, heavy-coated as 
he was, always worked without much apparent discomfort, 
and often accompanied me over Taylor’s Range on the hottest 
days, sharing only the contents of a small flask carried on 
my belt, out of which he learned to drink as I poured
