No one who reads the Gardeners' Monthly paints the pipes with gas tar; but there are some who have not this good fortune, and they, after getting into trouble, worry our readers to help them out. Hitherto no successful remedy has been known, but to take down the pipes and burn out the enemy. This will scarcely do on a cold night. As well leave the creosotic fumes to do the work as Jack Frost. But in the Old World they have unlucky people who cannot subscribe to horticultural periodicals - as well as here. One of them got into trouble, and this is what a correspondent of the Gardeners' Chronicle advises in regard thereto : " I think Mr. Bishop will be able to remove the tar from his hot-water pipes by first coating them with muriatic acid, or with vitriol diluted in water, and then afterwards washing them with water. It would be the best plan to wash them with a brush, as great care must be taken that none of the mixture touches the hands".
