The year is divided into four periods or seasons, the recurrence of which is indicated by the increase or diminution of the daylight. Immediately after the winter solstice the days begin to increase, and by the time of the vernal equinox, or in other words, in ninety days and three hours, the day is equal in length to the night. After this, for ninety-four days and twelve hours, the days continue to increase, and the nights to diminish in proportion, up to the summer solstice; and from that point the days, though gradually decreasing, are still in excess of the nights for ninety-two days, twelve hours, until the autumnal equinox. At this period the days are of equal length with the nights, and after it they continue to decrease inversely to the nights until the winter solstice, a period of eighty-eight days and three hours. In all these calculations, it must be remembered, equinoctial[427] hours are spoken of, and not those measured arbitrarily in reference to the length of any one day in particular. All these seasons, too, commence at the eighth degree of the signs of the Zodiac. The winter solstice begins at the eighth degree of Capricorn, the eighth[428] day before the calends of January, in general;[429] the vernal equinox at the eighth degree of Aries; the summer solstice, at the eighth degree of Cancer; and the autumnal equinox at the eighth degree of Libra: and it is rarely that these days do not respectively give some indication of a change in the weather.
These four seasons again, are subdivided, each of them, into two equal parts. Thus, for instance, between the summer solstice and the autumnal equinox, the setting of the Lyre,[430] on the forty-sixth day, indicates the beginning of autumn; between the autumnal equinox and the winter solstice, the morning setting of the Vergiliæ, on the forty-fourth day, denotes the beginning of winter; between the winter solstice and the vernal equinox, the prevalence of the west winds on the forty-fifth day, denotes the commencement of spring; and between the vernal equinox and the summer solstice, the morning rising of the Vergiliæ, on the forty-eighth day, announces the commencement of summer. We shall here make seed-time, or in other words, the morning setting of the Vergiliæ, our starting-point;[431] and shall not interrupt the thread of our explanation by making any mention of the minor constellations, as such a course would only augment the difficulties that already exist. It is much about this period that the stormy constellation of Orion departs, after traversing a large portion of the heavens.[432]
CHAP. 60.—THE PROPER TIME FOR WINTER SOWING.
Most persons anticipate the proper time for sowing, and begin to put in the corn immediately after the eleventh day of the autumnal equinox, at the rising of the Crown, when we may reckon, almost to a certainty, upon several days of rainy weather in succession. Xenophon[433] is of opinion, that sowing should not be commenced until the Deity has given us the signal for it, a term by which Cicero understands the rains that prevail in November. The true method to be adopted, however, is not to sow until the leaves begin to fall. Some persons are of opinion that this takes place at the setting of the Vergiliæ, or the third day before the ides of November, as already stated,[434] and they carefully observe it, for it is a constellation very easily remarked in the heavens, and warns us to resume our winter clothes.[435] Hence it is, that immediately on its setting, the approach of winter is expected, and care is taken by those who are on their guard against the exorbitant charges of the shop-keepers, to provide themselves with an appropriate dress. If the Vergiliæ set with cloudy weather, it forebodes a rainy winter, and the prices of cloaks[436] immediately rise; but if, on the other hand, the weather is clear at that period, a sharp winter is to be expected, and then the price of garments of other descriptions is sure to go up. But as to the husbandman, unacquainted as he is with the phænomena of the heavens, his brambles are to him in place of constellations, and if he looks at the ground he sees it covered with their leaves. This fall of the leaves, earlier in one place and later in another, is a sure criterion of the temperature of the weather; for there is a great affinity between the effects produced by the weather in this respect, and the nature of the soil and climate. There is this peculiar advantage, too, in the careful observation of these effects, that they are sure to be perceptible throughout the whole earth, while at the same time they have certain features which are peculiar to each individual locality.—A person may perhaps be surprised at this, who does not bear in mind that the herb pennyroyal,[437] which is hung up in our larders, always blossoms on the day of the winter solstice; so firmly resolved is Nature that nothing shall remain concealed from us, and in that spirit has given us the fall of the leaf as the signal for sowing.
Such is the true method of interpreting all these phænomena, granted to us by Nature as a manifestation of her will. It is in this way that she warns us to prepare the ground, makes us a promise of a manure, as it were, in the fall of the leaves, announces to us that the earth and the productions thereof are thus protected by her against the cold, and warns us to hasten the operations of agriculture.
CHAP. 61.—WHEN TO SOW THE LEGUMINOUS PLANTS AND THE POPPY.
Varro[438] has given no other sign but this[439] for our guidance in sowing the bean. Some persons are of opinion that it should be sown at full moon, the lentil between the twenty-fifth and thirtieth day of the moon, and the vetch on the same days of the moon; and they assure us that if this is done they will be exempt from the attacks of slugs. Some say, however, that if wanted for fodder, they may be sown at these periods, but if for seed, in the spring. There is another sign, more evident still, supplied us by the marvellous foresight of Nature, with reference to which we will give the words employed by Cicero[440] himself:
“The lentisk, ever green and ever bent
Beneath its fruits, affords a threefold crop:
Thrice teeming, thrice it warns us when to plough.”
One of the periods here alluded to, is the same that is now under consideration, being the appropriate time also for sowing flax and the poppy.[441] With reference to this last, Cato gives the following advice: “Burn, upon land where corn has been grown, the twigs and branches which are of no use to you, and when that is done, sow the poppy there.” The wild poppy, which is of an utility that is quite marvellous, is boiled in honey as a remedy for diseases in the throat,[442] while the cultivated kind is a powerful narcotic. Thus much in reference to winter sowing.
