Recently the Mennonites of Pennsylvania have been introduced into modern literature in a romance, the motive of which is an effort to show their disregard for learning. It is rather remarkable that the dawn of our science of pedagogy and the most extensive literary production of the American colonies were both due to the efforts of these interesting people. Dr. Martin G. Brumbaugh, the able Superintendent of the public schools of Philadelphia, has assumed the congenial task of gathering into this volume all of the works of Dock, in order that they may have a wider circulation among the reading public. It is fortunate for the future fame of the venerable Schoolmaster that his accomplishment has been appreciated by one so entirely capable of doing him justice and whose industry has left no source of information uninvestigated.
