?The author, George A. Martin, knows his subject, not only fence building but the farm and its requirements. He knows the stock: the unconfinable pig, the dexterous cow. He knows his materials, especially wood. I count twenty-one species of tree in the text, each especially suited for a particular application. He knows the value of work well done, done to last, and he aims to give value himself, in authorship as in the building of simple necessary structures.? from the Foreword by Castle Freeman
