Sir J.E. Smith, in his "English Flora," after enumerating the virtues of the hornbeam as a hedge plant, gives it as his opinion that "when standing by itself and allowed to take its natural form, the hornbeam makes a much more handsome tree than most people are aware of." Those who are familiar with the fine specimens which exist at Studley Park and elsewhere will have no hesitation in confirming Sir J.E. Smith's statement. The Hornbeam Walk in Richmond Park, from Pembroke Lodge toward the Ham Gate, will recur to many Southerners as a good instance of the fitness of the hornbeam for avenues. In the walk in question there are many fine trees, which afford a thorough and agreeable shade during the summer months. [Illustration: CARPINUS VIMINEA.] In any soil or position the hornbeam will grow readily, except exceedingly dry or too marshy spots. On chalky hillsides it does not grow so freely as on clayey plains. Under the latter conditions, however, the wood is not so good. In mountainous regions the hornbeam occupies a zone lower than that appropriated by the beech, rarely ascending more than 1,200 yards above sea level. It is not injured by frost, and in Germany is often seen fringing the edges of the beech forests along the bottom of the valleys where the beech would suffer. Scarcely any tree coppices more vigorously or makes more useful pollards on dry grass land. [Illustration: BRANCH OF CARPINUS BETULUS.] On account of its great toughness the wood of the hornbeam is employed in engineering work for cogs in machinery. When subjected to vertical pressure it cannot be completely destroyed; its fibers, instead of breaking off short, double up like threads, a conclusive proof of its flexibility and fitness for service in machinery (Laslett's "Timber and Timber Trees"). According to the same recent authority, the vertical or crushing strain on cubes of 2 inches average 14.844 tons, while that on cubes of 1 inch is 3.711 tons.
