that these estimates are made for soils that are completely exhausted 5 

 a condition in ^vhich, fortunately, but few of our American fields are 

 found. We may, therefore, safely reduce the quantity per acre in i)ro- 

 portion to the elements of fertility already in the soil. Scarcelj^ an in- 

 stance will occur in our country where it will be necessary or i)roper to 

 depend exclusively on artificial manures. If due care be observed, the 

 stable and barn-yard will always furnish the chief supply of manure to 

 the American farmer, and chemical manures will be used only as auxili- 

 aries to supply the mineral elements lost in the grain and other pro- 

 ducts sold from the farm. Used for this purpose, and in conjunction 

 Avith barn-yard manure, "the cost of chemical fertilizers necessary will 

 be j^reatly reduced. 



The practical value of this book is impau^ed by the mistake of the 

 translator in not rendering the French weights, measures, and values 

 into English. With the intention of remedying this defect, a table of 

 English equivalents is appended to the preface, but this will not serve 

 the purpose with the mass of American readers. While we appreciate 

 the importance of familiarizing our people with the decimal system of 

 weights and measures, now adopted by most European nations, yet wo 

 think the better way to do this will be to present the corresponding 

 values together, so that the eye can catch them at once. If the trans- 

 lator had carried out on the same line in his table of kilograms, hectares, 

 and francs, their values in pounds, acres, and dollars, he would not only 

 have added much to the value of his book, but he would have contrib- 

 uted directly to a general knowledge of the French system of weights 

 and measures. We hope the publisher will remedy this defect in a sub- 

 sequent edition ; for the work is of too much value to those who desire 

 to understand the philosophy of vegetable nutrition to be thrown care- 

 lessly aside on account of a minor defect. 



Farm-Gardenikg and Seed-Growixg. By Francis Brill, formerly market-fjardener 

 and seed-grower at Newark, New Jersey ; 12mo, 151 pi:). Orange, Judd & Co., Now 

 York, 1872. 



As its title indicates, this little work contains full instructions in farm 

 or market gardening and seed-growing, and will be found of great value 

 to the amateur gardener. It contains a table giving the proper number 

 of plants or hills which should be grown on an acre of ground, of every 

 vegetable, plant, or vine grown in the market-garden. The author, in 

 his introductory remarks, says : 



lu preparing this book, I have endeavored to give plain, jn-actical directions, in mi- 

 nute detail, for growing vegetables and seeds, and have aimed to avoid all superfluous 

 matter, which, though it might be interesting to the general reader, would be of no 

 practical benefit to those for whom the Avork is more specially designed. I have 

 deemed it advisable to disx)ense with illusti'ations, which I admit are useful, to a cer- 

 tain extent, in giving to the reader a more vivid idea of the form and general appear- 

 ance of the subject under consideration ; but in these days of enterprise, almost every 

 seedsman's catalogue, as well as the works on gardening which have preceded this, and 

 the agricultural and horticultural journals, contain complete illustrations of all lead- 

 ing vegetables, implements, &c.
