The Home has every reason to be proud of its collies. It was a smooth-coated collie borrowed from the Home for Lost Dogs which figured so prominently in the last Military Tournament at the Agricultural Hall. The dog was borrowed for the purpose of testing the value of the German system of sending messages by these useful creatures during the progress of military operations in time of war. The dog was attached to a cyclist who rode the whole length of the hall—over bridges, ruts, and other difficulties in the way—the animal following him. Then the cyclist wrote a message, and tied it round the collie's neck. The way was pointed out to him, he took a silent view of the road before him, and then, with a sudden bark suggestive that he understood, away the collie went, and delivered the despatch safely as required. This dog is now the property of Major Crabb.

We are now nearing what is, perhaps, the most important part of the Battersea Home, the Infirmary—which is practically the condemned cell—the Lethal Chamber, and the Crematorium. The condemned cell is a huge kennel separated into two compartments, through the iron grating of which often as many as a hundred dogs are to be counted. It should be said that a dog is never put to death unless it is past all cure, and, further, that the means employed are as quick and humane as scientists have yet discovered. For many years the method of killing was by the administration of hydrocyanic acid, but Dr. B. W. Richardson, F.R.S., conclusively proved that the most painless way of causing death was by the use of narcotic vapour, and he superintended the erection of an excellent Lethal Chamber, which was finished in May, 1884, and since then has been in constant use.

It is possible to narcotise as many as a hundred dogs at one time.
