General Douglas and the Rats.
The biographer of this highly-distinguished military engineer-officer relates an anecdote of him when a lieutenant at Tynemouth. The future author of well-known works on Gunnery and Military Bridges, early began to show ability in mechanics. "Lieutenant Douglas occupied a room barely habitable, and had to contest the tenancy with rats, which asserted their claim with such tenacity, that he went to sleep at the risk of being devoured. Their incursions compelled him to furnish himself with loaded pistols and a tinder-box, and he kept watch one night, remaining quiet till there was an irruption, when he started up and struck a light. But his vigilance proved of no avail, for the clink of the flint and steel caused a stampede, and not a rat remained by the time he had kindled the tinder. Their flight suggested to him another device. He looked out all the holes, and covered them with slides, connected with each other by wires, and these he fastened to a string, which enabled him to draw them all with one pull, and thus close the outlets. The contrivance claims to be mentioned as his first success in mechanics, foreshadowing his future expertness. It came into use the same night: he pulled the string without rising from bed, then struck a light, while the rats flew off to the holes to find them blocked, and he shot them at leisure. Two or three such massacres cleared off the intruders, and left him undisturbed in his quarters."[163]
