Dear Sir, The following suggestion to planters in swampy dis- tricts with tidal rivers may be of some value. Instead of the usual flood-gates adopt a hanging door on hinges with a weight at the bottom. The rough diagram below will show what I mean. This form of gate if properly constructed will not only prevent water from entering drains from the river, but will also at low tide permit of water escaping from the drains. Such gates should not cost much and will require little or no attention, besides the risk of jamming is reduced to a minimum. Yours faithfully, G.
