Excerpt from The New England Farmer, 1858, Vol. 10: A Monthly Journal, Devoted to Agriculture, Horticulture, and Their Kindred Arts and Sciences From the following, which we clip from the Country Gentleman, it will be seen that the French Government has employed a Mr. Duman, of Paris, to construct maps exhibiting the character of the sub-soil of the whole of France, to be ac companied with others of the geographical and geological features of the country. It is due to a citizen of Maryland, who for many years, and entirely at his own cost, has most industriously pursued the investigation of the qualities of the soil and sub-soil, to claim for him the credit of a method to which the French government attach es so much importance. Professor Baer, of Car roll Co., some fifteen years ago lectured before the Legislature of Maryland, with maps variously colored, to show the variations in the sub-soil, and has since been pursuing and perfecting his plans, and has now on hand a considerable col lection of such maps, handsomely executed, and showing to the eye at a glance the character and variation of sub-soils, which have been the sub ects of his investigations, as well as the remark able effect upon the growth of plants of a sub soil containing noxious elements underlying a go nial surface soil. Professor Baer pursues the same method in teaching Chemistry, having large maps on which are displayed for instance the whole number of bases and acids, and the pro portion in which they combine and their degrees of affinity indicated in such a way that the learn er gets the lesson with remarkable facility.
