"Subsoil" Quotes from Famous Books



... countries of abundant rainfall, a great distinction exists between the soil and the subsoil. The soil is represented by the upper few inches which are filled with the remnants of decayed vegetable matter and modified by plowing, harrowing, and other cultural operations. The subsoil has been profoundly modified by the action of the heavy rainfall, which, in soaking ...

... minutes the detective and the volcanologist joined him in the cavern. The top surface of the ground was rolled up into waves like the sea. The sides of the hole were almost sheer. The naked rock was exposed for thirty feet. Above the rock could be seen the subsoil, and then the layer of top soil and vegetation. Dr. Bird was carefully ...

... by removing the surface-soil to the depth of about three feet, a work of no small labour, until the subsoil, or "pay-dirt," was reached. Of this they dug out a small quantity, and washed it; put the produce of black sand and gold into leathern bags, and then, digging out another panful, washed it as before. Thus they laboured till ...

... remains. The huge banks of rock salt often met with in the vicinity of sulphur mines, and which in some places stretch for a distance of several miles, seem to indicate that the sea has worked its way into the subsoil. Fish and insects, which are frequently found in strata of tripoli, which lie under sulphur beds, induce the belief that lakes ...

... is applied and slow combustion goes on, most of the products of the burning being retained in the ground, much of the soil is incinerated. The final preparation is effected by the men digging up the subsoil round the mound, passing each hoeful into the left hand, where it pulverizes, and is then thrown on to the heap. It is thus virgin soil on the top of the ashes and burned ground of the original heap, very clear of weeds. At present ...

... region are imperfect valleys which have no outlet. As a consequence of this, the water cannot escape by an overground bed, so it forces itself through the porous surface to reappear in a lower valley, undermining the subsoil, which in time collapses, and forms the oases of this otherwise barren land. The rain washes down the little earth that there is on the hillside, the chemical action of the limestone oxidises the same, and the so-called "terra rossa" is formed in these depressions, sufficient to give ...

... aided by the situation, locality, and appearance of the soil, whether a certain portion of land is fitted for the profitable growth of any particular plant. Depth of soil, and facilities for deepening it, with the nature of the subsoil, so as to know whether it retains or parts with water, are also important considerations, because tap-rooted plants require free scope for ...

... century, this miserable village, with various other hamlets and almost all the cottages attached to farms on the Melrose estate, were the scandal of the countryside. Roofs that let in rain and wind, clay floors, a subsoil soaked in every possible abomination, bedrooms "more like dens for wild animals than sleeping-places for men and women," to quote a recent Government report, and a polluted water supply!—what more could reckless human living, aided by human carelessness and cruelty, have done ...

It was his personal spontaneity, similar to that of Emerson, and his personal vitality, similar to that of nobody else. Convictions and ideas came to him, so to speak, from the subsoil. He had a prophetic sympathy with the dawning sentiments of the age, with the moods of the dumb majority. His scattered words caught fire in many parts of the world. His way of thinking and feeling represented the true America, and represented in a ...

... pecan belt made at one time. Next to the neglect, which some of the planters allowed their orchards to undergo, probably the selection of the wrong kind of land has been the cause of more disappointment than any other one source. A fertile soil deep, mellow, well drained sandy or gravelly clay subsoil should be ideal for pecans anywhere in the latitude in which they are hardy. However, many other types of soil are producing pecans, and if your home happens to be located where the soil is not ideal, you can still grow them by furnishing the elements ...

... exalted or seemingly improved condition, whether of plant or animal, induced by human interference, is not the true and artistical ideal of it.[35] It has been well shown by Dr. Herbert,[36] that many plants are found alone on a certain soil or subsoil in a wild state, not because such soil is favorable to them, but because they alone are capable of existing on it, and because all dangerous rivals are by its inhospitality removed. Now if we withdraw the plant from this position, which it hardly ...

... glades of the wood at Misdon, perforated by galleries and cells, out of which came and went a mysterious society, was called 'The Great City.' The gloomy Breton forests were servants and accomplices of rebellion. The subsoil of every forest was a sort of sponge, pierced and traversed in all directions by a secret highway of mines, cells and galleries. Each of these blind cells could shelter five or six men. Usually the cover, made of moss and branches, ...

"Sam Slick," with his usual force and aptitude of illustration, says that "she goes through the water like a subsoil-plough with an eight-horse team." There is so much noise and groaning, and smoke and dirt, so much mystery also, and the ship leaves so much commotion in the water behind her. There do not seem to be any regular ...

... those who for the most part have nothing to do at the end of the race, which they run as if they were so many Mercuries speeding with messages from Jupiter. Look at our scientific drainage, which turns refuse into poison. Look at the subsoil of London, whenever it is turned up to the air, converted by gas leakage into one mass of pestilent blackness, in which no vegetation can flourish, and above which, with the rapid growth of the ever-growing nuisance, no living thing will breathe with impunity. Look at our scientific ...

... streaks of red, will drop from its track, and it will leave a wake, six or seven times as wide as a high road, from which all soil, all cultivation, all semblance to cultivated or cultivatable land will have disappeared. It will not even be a track of soil. It will be a track of subsoil laid bare. It will be a flayed strip of nature. In the course of its fighting the monster may have to turnabout. It will then halt and spin slowly round, grinding out an arena of desolation with a diameter equal to its length. If it has to retreat and advance again these streaks ...

... be deep and porous, so that the roots will strike far into it, and be enabled thereby to withstand droughts and cold winters. The best means of deepening the soil, as explained in Chapter IV, is by tile-draining; but it can also be accomplished to some extent by the use of the subsoil plow and by trenching. Since the lawn cannot be refitted, however, the subsoil is likely to fall back into a hard-pan in a few years if it has been subsoiled or trenched, whereas a good tile-drain affords a permanent ...

As far as that goes we have ploughed it up a bit already, but a systematic ploughing will make it more regular. The subsoil is only four inches, then you come to chalky clay.

The examination was to include digging to ascertain the depth of the soil and the nature of the subsoil.

... the surface of the prairie, and often in especially dry seasons cattle would perish were not these faithful little well-diggers and pumpers constantly at work for them. In the river valleys of Arizona although the air is dry the subsoil water is near the surface of the ground. Here flourishes the mesquit tree, Prosopis juliflora, with a tale to tell well worth knowing. When a mesquit seems stunted, it is because its strength is withdrawn for the task of delving to find water; where a tree grows ...

When the inundation was over, the subsidence of the water which impregnated the subsoil caused in course of time settlements in the most solid foundations: the walls, disturbed by the unequal sinking of the ground, got out of the perpendicular and cracked; this shifting displaced the architraves which held the columns ...

... placed his house in Cheshire at Cavour's disposal to give him an opportunity of studying English agriculture. The chance was not thrown away. Cavour learnt everything about the management of a well-ordered English estate down to the minutest particulars. He admired much, especially the system of subsoil drainage, then a novelty to foreigners, but he was not carried away by the beautiful appearance of the English country so far as to think that the English farmer was in all respects ahead of the North Italian. ...

... rainfall and temperature, and only secondarily on soil. A desert is a tract with a dry substratum and dry air, great heat during some part of the year, and bright sunshine. The soil may be loam or sand, and as regards vegetation a sandy desert is the worst owing to the rapid drying up of the subsoil after rain. In the third of the maps appended to Schimper's Plant Geography by far the greater part of the area dealt with in this book is shown as part of the vast desert extending from the Sahara to Manchuria. Seeing that the monsoon ...
