By Lewis Castle, of the Journal of Horticulture, London; sold also by Chas. H. Marot, Philadelphia.

This is a very timely little book, for there never was a period in the history of American Horticulture when a knowledge of cactuses was more sought for than now. They do not as a rule remain long in flower, but this very fact gives zest to the anticipation to see them blossom. But - and this is perhaps one of the most remarkable features about them - though so short a time in blossom, they mostly come into bloom at different times, so that one who has a large collection, may have cactus flowers almost any time in the year. Cactuses are all natives of the New World, so although this is an English work it treats of American plants and thus will be very welcome. Some fifteen are figured, a large number described, and useful hints for culture adapted to all.
