“Produce 2½ tons of clover-hay, and 3 cwt. of seed per acre.
“This soil was obtained within a distance of five yards from the part of the field where the soil was dug up after the two cuttings of hay. After the seed there was some difficulty in finding a square foot containing the same number of large clover-roots, as that on the field twice mown; however, at last, in the beginning of November, a square foot containing exactly 18 strong roots, was found and dug up to a depth of 18 inches. The soil dug after the seed was much drier than that dug after the two cuttings of hay:
| The upper six inches deep, one foot square, weighed … … … | 56 lbs. |
| The next six inches deep, one foot square, weighed … … … | 58 lbs. |
| The third six inches deep, one foot square, weighed … … … | 60 lbs. |
“After drying by exposure to hot air, the three layers of soil weighed:
| The upper six inches, one foot square … … … | 49¾ lbs. |
| The next six inches, one foot square … … … | 50½ lbs. |
| The third six inches, one foot square … … … | 51¼ lbs. |
“Equal portions of the dried soil from each six-inch section were mixed together and reduced to a fine powder. An average sample thus prepared, on analysis, was found to have the following composition:
| Soluble in hydrochloric Acid | Organic matter | 5.34 |
| Oxides of iron | 6.07 | |
| Alumina | 4.51 | |
| Carbonate of lime | 7.51 | |
| Magnesia | 1.27 | |
| Potash | .52 | |
| Soda | .16 | |
| Chloride of sodium | .03 | |
| Phosphoric acid | .15 | |
| Sulphuric acid | .19 | |
| Insoluble in acid | Insoluble silicious matter, 73.84. | |
| Alumina | 4.14 | |
Lime (in a state of silicate) | 2.69 | |
| Magnesia | .68 | |
| Potash | .24 | |
| Soda | .21 | |
| Silica | 65.88 | |
| 99.59 |
“The soil, it will be seen, in general character, resembles the preceding sample; it contains a good deal of potash and phosphoric acid, and may be presumed to be well suited to the growth of clover. It contains more carbonate of lime, and is somewhat lighter than the sample from the part of the field twice mown for hay, and may be termed heavy calcareous clay.
“An acre of this land, 18 inches deep, weighed, when very nearly dry:
