Diseases of Plants. By H. Marshall Ward. (S.P.C.K.)—Mr. Ward treats

such well-known plant-diseases as the " rust " of wheat, " ergot " of rye, "smut" of corn, and others only too well known to farmers and gardeners, very clearly, so that every one can read for himself. To this day the majority of those who suffer from the "potato-disease," "club-root," and " damping-off" have but the crudest ideas as to the nature of their enemy. Diseases of Plants belongs to "The Romance of Science Series," to which also belong "Time and Tide" and "The Story of a Tinder- Box ;" and being such a vital subject, should prove even more useful.
