Abstract
THIS is a collection of forty exercises on soils. The book consists of forty sheets of scribbling paper held together by paper-fasteners inside a brown paper cover, so that each sheet may be used separately by the scholars and then bound up again with the rest. Each page has a few lines of printed directions at the top, followed in many cases by a ruled form in which the student is intended to enter his results.
