=Bacteria of the Dairy.=--An investigation of the relation of acid fermentation to the flavor and aroma of butter, made by C. H. Eckles at the Iowa College Experiment Station, has given the results that the flavor is produced by the bacterial fermentations which have taken place in the milk and cream. The kind of flavor depends upon the class of bacteria causing the fermentation. The ripening of a good quality of acid cream is mostly a development of acid bacteria. Four species of acid-producing bacteria, tested in ripening pasteurized cream, were found to give the butter the typical flavor and aroma. Of the species tried, the most common milk-souring organism (_Bacterium lactarii_) was found to give the most satisfactory results in ripening cream. Cream ripened with common bacteria found in hay dust (_Bacillus subtilis_) gives a very undesirable flavor to butter. The superior flavor of summer butter is due to the greater number of bacteria of the acid class found in milk during that season. =For Outdoor Improvement.=--The American Park and Outdoor Association has taken up and aims to nationalize the important work of the improvement of outdoors. Not that it expects to improve upon Nature, but it hopes to be able to neutralize or remedy the devastation and disfigurement which man has wrought upon her face. At the third annual meeting of the association, held in Detroit in July, 1899, preliminary steps were taken toward offering prizes for the improvement of grounds about manufactories and homes--both front and back lots--and especially about the homes of artisans. A standing committee was instituted to consider the best way of checking abuses of public advertising. A paper read by Mr. F. Law Olmstead, on the Relation of Reservoirs to Public Parks, concerned such construction of reservoirs and the surrounding them with suitable settings as would bring them into closer harmony with the park landscape and make them more a part of it. Another paper, by Mr. R. J. Coryell, of the Detroit parks, might be described as an effort to show how a similar service may be performed for the parks and the people--in other words, how to make the people at home in the parks. Its points were illustrated by citing what had been done in Detroit. Respecting means of preventing depredations, Mr. C. C. Lancey told of good results accomplished in Rochester, N. Y., by the distribution of circulars of information on the subject; and Mr. F. L. Olmstead, Jr., of the interest taken by the children in the school gardens in Cambridge, Mass.
