How to Cultivate and Preserve Celery. By Theophilus Roessle, of the Delavan House, Albany, N. Y. Edited, with a Preface, by Henry S. Olcott. - Mr. Roessle has for some years been known as a successful grower of Celery, and the present volume gives us the details of his practice. In some respects we should be loath to follow it. For example, he says Celery seed should be sown an inch deep. We doubt whether one seed in a hundred will vegetate at that depth; certainly not very speedily. The better and more usual plan is to sow the seed about a quarter of an inch deep. His manner of treating the plants in the hotbed we consider defective. It is a good plan, as be recommends, to let the weeds first come up; but he greatly errs in spading over the beds after destroying them, for he thereby insures the growth of a second crop, and his bed is no better than at the beginning. We have tried this too often not to be familiar with the result Our practice is to disturb the soil as little as possible in destroying the weeds: the celery (or whatever seed may be sown) then comes up comparatively clean.

The system of blanching by two earthings is quite common among gardeners; those, however, who wish to produce extra large and fine heads, repeat the earthing a number of times; but this repeated earthing Mr. Roessle condemns. There must be some merit in a plan, however, which produces fine, crisp, solid heads weighing from seven to nine pounds each. The plan recommended for preserving the plants is a good one, and has been very successful in the hands of the author. The secret of his success, however, in Celery growing, consists, in our opinion, in the thorough manner in which bis trenches are prepared; and bis views on this point should be carefully read. The volume is handsomely printed in large type, and the editor's finished pen is manifest on every page. The work is published by the author, but may be had of Saxton.
