Farm-Drainage.  The Principles, Processes, and Effects of Draining Land, with Wood, Stones, Ploughs, and Open Ditches, and especially with Tiles; including Tables of Rainfall, Evaporation, Filtration, Excavation, Capacity of Pipes; Cost, and Number to the Acre, of Tiles, etc., etc.; and more than One Hundred Illustrations.  By HENRY E. FRENCH.  New York:  A.O.  Moore & Co. 1859. 8vo. pp. 384.

We remember standing, thirty years ago, upon the cupola of a court-house in New Jersey, and, while enjoying the whole panorama, being particularly impressed with the superior fertility and luxuriance of one farm on the outskirts of the town.  We recollect further, that, on inquiry, we found this farm to belong to a Judge of the Court of Common Pleas, who also exercised the trade of a potter, and underdrained his land with tile-drains.  His neighbors attributed the improvement in his farm to manure and tillage, and thought his attempts to introduce tile-drains into use arose chiefly from his desire to make a market for his tiles.  Thirty years have made a great change; and a New Hampshire Judge of the Court of Common Pleas gives us a book on Farm-Drainage which tells us that in England twenty millions of dollars have been loaned by the government to be used in underdraining with tile!

We believe that Judge French has given the first practical guide in draining to the American farmer,—­indeed, the first book professing to be a complete practical guide to the farmers of any country.  His right to speak is derived from successful experiments of his own, from a visit to European agriculturists, and from a personal correspondence with the best drainage-engineers of England and America, as well as from the study of all available magazines and journals.  No one could handle the subject in a more pleasant and lucid style; flashes of wit, and even of humor, are sparkling through every chapter, but they never divert the mind of the reader from the main purpose of elucidating the subject of deep drainage.  The title-page does not promise so much as the book performs; and we feel confident that its reputation will increase, as our farmers begin to understand the true effects of deep drainage on upland, and seek for a guide in the improvement of their farms.

The rain-tables, furnished by Dr. E. Hobbs, of Waltham, afford some very interesting statistics, by which our climate may be definitely compared with that of our mother country.  In England, they have about 156 rainy days per annum, and we but 56.  In England, one inch in 24 hours is considered a great rain; but in New England six inches and seven-eighths (6.88) has been known to fall in 24 hours.  In England, the annual fall is about 21,—­in New England, 42 inches.  The experiments on the retention of water by the soil are also interesting; showing that ordinary arable soil is capable of holding nearly six inches of water in every foot of soil.
