The two swales in the front and rear of the house appeared like mill-ponds. In the former instance, the water had backed up from the mountain stream into which my drain emptied, and, therefore, it could not pass off; and in the latter instance I could scarcely expect my little underground channel to dispose at once of the torrents that for forty hours had poured from the skies. I must give it at least a night in which to catch up. And a busy night it put in, for by morning it had conveyed to depths unknown the wide, discolored pond, that otherwise would have smothered the plants it covered. As soon, also, as the mountain stream fell below the mouth of the lower drain, it emptied at once the water resting on the lower swale. Throughout the day came successive tales of havoc and disaster, of dams scooped out, bridges swept away, roads washed into stony gulches, and fields and gardens overwhelmed with debris. The Idlewild brook, that the poet Willis made so famous, seemed almost demoniac in its power and fury. Not content with washing away dams, roads, and bridges, it swept a heavy wall across a field as if the stones were pebbles.
My three diverse systems of drainage had thus practically stood the severest test, perhaps, that will ever be put upon them, and my grounds had not been damaged to any extent worth naming. The cost had been considerable, but the injury caused by that one storm would have amounted to a larger sum had there been no other channels for the water than those provided by nature.
My readers will find, in many instances, that they have land which must be or may be drained. If it can be done sufficiently, the very ideal strawberry soil may be secured—moist and deep, but not wet.
CHAPTER IX
THE PREPARATION OF SOILS COMPARATIVELY UNFAVORABLE—CLAY, SAND, ETC.
We have now reached a point at which we must consider land which in its essential character is unfavorable to strawberries, and yet which may be the best to be had. The difficulties here are not merely accidental or remediable, such as lack of depth or fertility, the presence of stones or stumps, undue wetness of soil, etc. Any or all of these obstacles may be found, but in addition there are evils inseparable from the soil, and which cannot be wholly eradicated. The best we can hope in such a case is to make up by art what is lacking in nature.
This divergence from the deep, moist sandy loam, the ideal strawberry land, is usually toward a stiff, cold, stubborn clay, or toward a droughty, leachy sand that retains neither fertility nor moisture. Of course, these opposite soils require in most respects different treatment.
We will consider first the less objectionable, that is, the heavy clay. To call clay more favorable for strawberries than sandy land may seem like heresy to many, for it is a popular impression that light soils are the best. Experience and observation have, however, convinced me of the contrary. With the clay you have a stable foundation. Your progress may be slow, but it can be made sure. The character of a sandy foundation was taught centuries ago. Moreover, all the fine foreign-blooded varieties, as well as our best native ones, grow far better on heavy land, and a soil largely mixed with clay gives a wider range in the choice of varieties.
If I had my choice between a farm of cold, stiff clay or light, leachy land, I would unhesitatingly take the former, and I would overcome its native unfitness by the following methods: If at all inclined to be wet, as would be natural from its tenacious texture, I should first underdrain it thoroughly with tile. Then, if I found a fair amount of vegetable matter, I would give it a dressing of air-slaked lime, and plow it deeply late in the fall, leaving it unharrowed so as to expose as much of the soil as possible to the action of frost. Early in the spring, as soon as the ground was dry enough to work and all danger of frost was over, I would harrow in buckwheat and plow it under as it came into blossom; then sow a second crop and plow that under also. It is the characteristic of buckwheat to lighten and clean land, and the reader perceives that it should be our constant aim to impart lightness and life to the heavy soil. Lime, in addition to its fertilizing effects, acts chemically on the ground, producing the desired effect. It may be objected that lime is not good for strawberries. That is true if crude lime is applied directly to the plants, as we would ashes or bone-dust; but when it is mixed with the soil for months, it is so neutralized as to be helpful, and in the meantime its action on the soil itself is of great value. It must be used for strawberries, however, in more limited quantities than for many other crops, or else more time must be given for it to become incorporated with the soil.
The coarse green straw of the buckwheat is useful by its mechanical division of the heavy land, while at the same time its decomposition fills the soil with ammonia and other gases vitally necessary to the plant. A clay soil retains these gases with little waste. It is thus capable of being enriched to almost any extent, and can be made a storehouse of wealth.
