"The walnut tree has a great variety of good qualities in addition to its fine appearance and generous shade. From the kernel a valuable oil may be obtained for use in cookery and in lamps. Bread has also been made from the kernels. The spongy husk of the nuts is used as dyestuff. It thus unites almost all the qualities desirable in a tree--beauty, gracefulness and richness of foliage in every period of its growth; bark and husks which may be employed in an important art; fruit valuable as food; wood unsurpassed in durability and in elegance."
