Mr. Hippard says : "I have noticed the article published by you in January-number of Gardeners' Monthly as an editorial. You have made a grand mistake when you say the way in which the glass is used would enable 25,000 feet to be used in this way instead of 12,000. This is not the fact; Stover says that we could put on our lot 25.000 square feet of glass, and any neighbor can truthfully say that our lot is half covered over with glass, thus making upwards of 12,000 square feet used to propagate and grow our plants, - or about one-half of our ground covered by glass".
