Sentry and Single are brother and sister, being by Sixty out of Scottie, but the photograph of the former scarcely does him justice, as it was taken when he was little more than a year old, and it makes him appear too throaty. His coat, moreover, is finer than it looks in the illus- tration, and he certainly stands more upriglit on his feet than portrayed. He is, in fact, a typical Labrador, but if anything a little narrow between the eyes, whilst his tail is a trifle long.
The group of the Hon. A. Holland-Hibbert and his dogs includes the quartette above referred to, and, in addition, Sarah, the dam of Sixty, Sud- bourne, Psaltery, and Sober, every one of which may be accepted as a typical specimen of a most valuable variety of sporting dog which is far too seldom met with in this country.

The Labrador retriever, Sentry, was bred by, and is the
property of, the Hon. A. Holland-Hibbert. His sire was Sixty
and his dam Scoltie, and he was born in April 1900. He stands 23 inches at shoulder, weighs 65 Ibs., and is an all-black dog, without any white hairs. His eyes are light, the carriage of his ears correct, upright rather when called, tail straight, coat thick and quite straight, splendid shoulders and loins, and hocks well let down. To hint a defect, his tail is a trifle too long, and not sufficiently like an otter's. The photo was taken before he was fully furnished, and he has improved considerably.
