frequent breakings of the Ground make way for the Waters of Rain, and make them pene∣trate towards the Roots, which stand in need thereof; whereas otherwise they would remain upon the Surface, where they would be of no use, and soon after evaporate: Tillage like∣wise makes a passage for heat, without which Moisture can be of no use.
On the contrary, Cold, Strong, Moist Earth, must never be Till'd in time of Rain, but rather during the greatest Heats, at which time they can neither be Till'd too often nor too deep, especially to hinder them from parching and splitting on the Top, which, as we have often said, does a great deal of prejudice to the Roots; and to the End, that it being softned by Tillage, the heat may penetrate the easier to them, and thereby may destroy the Cold, which hinders the Action of the Roots, and makes Trees yellow.
The Nature of the Earth shews us in this, as well as in many other Things, that it will be order'd regularly, so that it answers our Intentions with success, when it is pru∣dently manag'd; whereas, on the contrary, it opposes them when it is govern'd Ill: The Season of putting most Coin into the Ground, which commonly are only sown each in one Season, the time of Graffing, of Pruning and of Planting Vines as well as Trees, &c. which likewise is only done in certain Months; all these, I say, are so many Instructions which Nature gives us, in order to teach us how to study well what the Ground requires, and pre∣cisely at what time. By those Observations, a great Application has taught me, that it is good to Till often about Trees, either in dry, light Earths, or in such as are strong and moist; the one in rainy Weather, and the other in great Heats.
Those frequent Tillings, which I advise, when Convenience will permit it, are of great Use; for, besides their hindring part of the Goodness of the Earth from being exhausted by the Production and Nourishment of ill Plants; they, on the contrary, make those Weeds which Rot, being laid under Ground, serve for an Amendment to fatten it; but moreover those frequent Tilths partly destroy the Ancient Maxims, which had Establish'd but one Tillage for every Season; and what I like most in them is, that, at least, they establish the Necessity, and consequently the Usefulness of them: But I add, that they are not sufficient, unless, during their Intervals, care be taken to scrape, or pull out those ill Weeds, which especially in the Summer and in Autumn, grow upon Earths, and then Mul∣tiply, ad Infinitum, when they are suffer'd to run up to Seed.
We must say here by the by, that the times in which Trees bloslom, and the Vine shoots are very dangerous for Tillage, it must never be performed at those Times, neither about those Trees or Vines; the Earth being newly stir'd in the Spring, exhales abundance of Va∣pours, which upon the least white hoary Frosts, which are common at that Season, being stopt near the Surface of the Earth, stick upon the Blossoms, soften and moisten them, in so much that rendring them susceptible to the Frost, they contribute to kill them; Earths that are not Till'd at that time, and consequently are hard about the Surface, are not sub∣ject to exhale so many Vapors, and therefore not subject to so many Accidents of Frost.
From what I have said heretofore to favour the Nourishment of our Trees, it follows, that I condemn those who Sow or Plant, either many Pot-herhs, or Strawberries, or Flowers, near the Foot of their Trees, such Plants being certainly very prejudicial to them.
The Rule I Practise for the Culture or Tillage, that is to be perform'd about our Trees, as well in the Winter as in the Spring, in dry light Earths, is to allow them a large one at the Entrance of the Winter, and the like as soon as it is past, to the end that the Rains and Snows of the Winter, and the Rains of the Spring, may easily penetrate into our Earth; and as for the strong and moist Earths, I give them a small Tillage in the Month of October, only to remove the Weeds, and tarry to give them a large one at the end of April, or the beginning of May, when the Fruit is absolutely knit, and the great Moistures over; thus the Surface of that Earth being kept hard, firm and close, has left but little passage for the Waters of the Winter and Spring, which we have no occasion here, for the Snow being melted, without having been capable of penetrating, remains part upon the Surface, where it is converted into Vapors, and the rest following the Declivities of the Place, descends into the Neighbouring Rivers.
I must needs say, in this Place, that nothing moistens so much, and penetrates so far as the Water of melted Snow. I have seldom known Water to penetrate above a foot deep, whereas the Water of Snow will penetrate two or three Foot, as well because it is heavier than common Rain Water, as by reason, that as it melts slowly and by degrees, and from the undermost part of the Mass of Snow, it soaks in with more ease, without being hindred by the Wind, or by the heat of the Sun.
Therefore, as much as I dread abundance of Snow upon strong, moist Grounds, and cause it to be remov'd from about our Fruit-Trees; I like it, and cause it to be gather'd in dry Earths, there to make a kind of Magazine of Moisture; and especially in those
