Uncle Roberts Visit is the third book in the series Uncle Robert's Geography of Appletons' Home Reading Books. This series is edited by Colonel Francis W. Parker, one of the most eminent and successful teachers in the country. He believes in putting life into the schools, and has done it wherever he has been, and designs the geography series to help teachers put life into their teaching in the primary classes. Uncle Robert comes to the farm and talks to the children, assisting them at the same time to observe and experiment, about the map of the farm, the thermometer, the animals, flowers, sunlight and shadow, barometer, woods, birds, thundershower, railroad, the rainy day, etc., and the things which these suggest and illustrate, always having the geographical bearing well in view. So far as is possible each child is left to discover facts for himself and make original inferences—an example which the teacher may follow to a reasonable extent, taking care that the child's desire for knowledge is in the end satisfied. The name of Nellie Lathrop Helm is associated with that of Dr. Parker in the authorship of the book. New York: D. Appleton & Co.

We have from the Macmillan Company the first four volumes of a series of six Science Readers for the schoolroom or the house, by Vincent T. Murché, revised and adapted by Mrs. L. L.

The lessons are consecutive in groups of which the members depend severally upon the preceding one, and concern tl;e properties of bodies; the nature, growth, and structure of plants; the common types of animals; minerals and metals; the phenomena of the weather; and, generally, the conditions around us.
