govropontents. nee:weans. Maple Sugar. To th.e Editor of the Scientific American: There is a short article headed 'Maple Sugar' in your is sue of April 27 in which the writer gives an account of the process of the manufacture of that sweet compound. He says that yearly all of our hard wood trees will yield more or hard wood trees will yield sap but I deny that nearly all of them will yield sugar. Take for instance the birch ; one birch tree of common size will yield more sap than two or three maple sugar trees will in the same length of time ; but the sap concentrated by boiling yields a compound as unlike Again he says : 'After the sap is drawn it is concentrated by boiling it until it commences to crystalize.' Now this is not ufacture of that desirable article. After the sap is drawn it is concentrated by boiling to the consistency of sirup but never until it crystalizes. When the sirup becomes thick enough to 'apron' (as the farmers call it) or when it will drop from a dipper (which they always have to stir the sap -sheets it is immediately removed from the fire and allowed -to cool or not as the maker of the sugar may desire. After it is removed from the fire it is dipped from the kettle or pan in which it is boiled into wooden pails or barrels. The next operation is to strain or filter the sirup through woolen cloth This done it is set away and the farmer can sugar it off at his conionience. If the sap were allowed to boil until it commenced to crys talize it would be impossible to filter the sirup ; consequent ly it would be of no value for the reason that it would be so full of dirt that it could not be used. When the farmer comes to 'sugar off' his sirup as it is called the kettle or pan is cleansed until it is perfectly clean. The sirup is then poured in and two or three eggs according to the quantity are well beaten and added to the sirup. This is to (Parise it from all impurities which rise to the top while Farmers never boil the sap that runs after the t
