A complete Manual for the Cultivation, Pruning and Management of all Plants suitable for American Hedging; to which is added a Treatise on Evergreens. By John A. Warder, M. D. New York: A. O. Moore, 1858.

This is a duodecimo of 291 pages, with illustrations, at the price of one dollar. It is a resume of what is known on the subjects it treats of, and might, in fact, be called " A Plea for the Osage Orange;" the reader will find it contains the two following paragraphs - the first from the author, the second from Mr. Ernst, on the Osage Orange:

Page 126

" The interfacings, as a remedy, would, by a good oultivator, be considered of doubtful propriety, to say the least, except in a very limited extent".

Page 192

"Plashing answers well; it is a simple process," etc. "Plaiting or plashing are the only safe modes of protection, and never should be dispensed with for an outside protection," etc.

It is true that Dr. Warder says: "For my own notions, as to the sentiments contained in the last paragraphs, the reader is referred to the appropriate chapter." The said chapter is intended to controvert the opinions of the Horticulturist, which are sustained by Mr. Ernst at page 192, in the fullest manner, one employing the word "interfacings," and the other " plaiting or plashing".

The last part, on evergreens, is intended for learners - the merest tyros in planting, and we submit to the author whether the use, to such, of words like "adnate" and "phytology" in common writing, is not giving too strong expressions for beginners, who may be obliged to turn to their dictionaries.

Again: we beg book-makers not to follow so frequently the example of the Patent Office in its "Reports." By general consent of naturalists and all scientific men, the Latin names attached to plants when they are significative of a place, a country, or a person, are spelled with a capital letter; Cedrus Libani and not libani; Abies Canadensis and not canadensis; see pages 258 and 254; and again, page 250, Pinus Australis is spelled with a small a, and the same error is repeated in sinensis, canariensis, etc. etc.; it has Californiana for Californica, etc., to say nothing of names being spelled different ways.

We regret that the writer has omitted the enumeration of one of the best, if not the best plant for an evergreen ornamental hedge, viz., the Siberian Arbor Vitae, Thuja Sibirica. We most willingly admit that mistakes are easily committed, and that our own printer allows errors sometimes to pass, but nevertheless make these suggestions for the benefit of future editions; the subject is an important one. Dr. Warder can do better.

With regard to the Osage Orange as a hedge plant, we indorse Professor J. B. Turner's opinion, that "the causes of failure have been, in most cases, imperfect preparation of the soil, poor plants, careless culture, or the intrusting of the job to professional hedge-makers, who were strangers to their employers".
