Página 68 - A farmer manures a field of four or five inches of free soil reposing on a retentive clay, and sows it with wheat. It comes up, and between the kernel and the manure it looks well for a time, but anon it sickens. An Irish child looks well for five or six years, but after that time potato-feeding, and filth, and hardship begin to tell.
Página 72 - I tell them lean not keep the rainwater out of socketed pipes, twelve feet deep, that convey a spring to my farm-yard. Let us try and convince this large class of doubters ; for it is of national importance. Four feet of good porous clay would afford a far better meal to some strong bean, or other tap roots, than the usual six inches ; and a saving of $4 to $5 per acre, in drainage, is no trifle.
Página 166 - ... and the county society awarded a premium to Mr. Johnston. Eight acres and some rods of this land, at one side, averaged 94 bushels, or the trifling increase of 84 bushels per acre over what it would bear before those in107 significant clay tiles were buried in the ground.
Página 167 - ... .if it does come, then draining will pay for itself speedily. For instance : Mr. Johnston had a lot of thirteen acres on the shore of the lake, where the bank at the foot of the lot was perpendicular to the depth of thirty or forty feet. He supposed from this fact, and because the surface seemed very dry, that he had no need to drain it. But somehow he lost his...

"That the method of removing refuse in suspension in " water by properly combined works, is much better than " that of collecting it in pits or cess-pools near or under" neath houses, emptying...
Página 165 - Mr. Johnston says he never saw one hundred acres in any one farm, but a portion of it would pay for draining. Mr. Johnston is no rich man who has carried a favorite hobby without regard to cost or profit. He is a hardworking Scotch farmer, who commenced a poor man, borrowed money to drain his land, has gradually extended his operations, and is now reaping the benefits, in having crops of forty bushels of wheat to the acre.
Página 239 - England to improve house-drainage and sewerage, as affecting public health, Mr. Waring concludes by stating that the principles of his book, whether relating to sanitary improvement, to convenience and decency of living, or to the use of waste matters of houses in agricultural improvement, are no less applicable in America than elsewhere; and the more general adoption of improved house drainage and sewerage, and of the use of sewage matters in agriculture, would add to the health and prosperity of...
Página 37 - The undrained soil never exceeded 47°, whereas after a thunder-storm the drained reached 66° at 7 inches, and 48° at 31 inches. Such were the effects at an early period of the year on a black bog. They suggest some idea of what they are, when in July or August thunder-rain at 60° or 70° falls on a surface heated to 130°, and carries down with it into the greedy fissures of the earth its augmented temperature. These advantages porous soils possess by nature, and retentive soils only acquire...
Página 213 - In considering the circumstances external to the residence which affect the sanitary condition of the population, the importance of a general land drainage is developed by the inquiries as to the causes of the prevalent diseases, to be of a magnitude of which no conception had been formed at the commencement of the investigation: its importance is manifested by the severe consequences of its neglect in every part of the country, as well as by its advantages in the increasing salubrity and productiveness...
