Roman Farm Management Part 9

_c. Cuttage_

In respect of cuttage, which consists in planting in the ground a live cutting from a tree, it behooves you especially to see that this is done at the proper time, which is before the tree has begun to bud or bloom: that you take off the cutting carefully rather than break it from the parent tree, because the cutting will be more firmly established in proportion as it has a broad footing which can readily put out roots: and that it is planted promptly before the sap dries out of it.

In propagating olives select a truncheon of new grown wood about a foot in length and the same size at each end: some call these _clavolae_ and others call them _taleae_.

_d. Graftage_

In respect of graftage, which consists in transferring growing wood from one tree to another, care must be taken in selecting the tree from which the scion is taken, the tree on which it is grafted, and the time and the manner in which it is done: for the pear cannot be grafted on an oak, even though it may upon the apple. In this operation many men who have great faith in the sayings of the soothsayers give heed to their warning that as many kinds of grafts there may be on a tree so many bolts of lightning will strike it, because a bolt of lightning is generated by each graft (_ictu_).[91]

If you graft a cultivated pear upon a wild pear tree no matter how good it may be, the result will not be as fortunate as if you had grafted on another cultivated pear. Having regard for the result, on what ever kind of tree you graft, if it is of exactly the same kind, as, for instance, apple on apple, you should take care that the scion comes from a better tree than that on which it is grafted.

_e. A "new" method--inarching_

There is another operation recently suggested,[92] for propagating one tree from another, when the trees are neighbours. From the tree from which you wish to take a scion a branch is trained to that on which you wish to make the graft and the scion is bound upon an incision in a branch of the stock. The place of contact of both scion and stock is cut away with a knife so that the bark of one joins evenly with the bark of the other at the point of exposure to the weather. Care should be taken that the growing top of the scion is pointed straight upwards. The following year when the graft has knitted, the scion may be cut from its parent tree.

_Of when to use these different methods_

XLI. The most important consideration in propagating is, however, the time at which you do it: thus things which formerly were propagated in the spring now are propagated in summer, like the fig, whose wood is not heavy and so craves heat, as a consequence of which quality figs cannot be grown in cold climates. For the same reason water is dangerous to a new fig graft because its soft wood rots easily. For these reasons it is now considered that midsummer is the best season to propagate figs. On the other hand it is the custom to tie a pot of water above a graft of hard wood trees so that it may drip on the graft and prevent the scion from drying up before it has been incorporated with the stock. Care must be taken that the bark of the scion is kept intact, and to that end it should be sharpened but so that the pith (_medulla_) is not exposed. To prevent the rain or the heat from injuring it from without, it should be smeared with clay and bound with bark. It is customary to take off the scion of a vine three days before it is to be grafted so that the superfluity of moisture may drain out before the scion is inserted, or, if the graft is already in place, an incision is made in the stock a little below the graft from which the advent.i.tious moisture may drain off: but this is not done with figs and pomegranates, for in all trees of a comparatively dry nature the graft is made immediately. Indeed, some trees, like the fig, are best grafted when the scion is in bud.

Of the four kinds of propagation which I have discussed, that of graftage is preferred in respect of those trees which, like the fig, are slow in developing: for the natural seeds of the fig are those grains seen in the fruit we eat and are so small as scarcely to be capable of sprouting the slenderest shoots. For all seeds which are small and hard are slow in germinating, while those which are soft are more spontaneous, just as girls grow faster than boys. Thus by reason of their feminine tenderness the fig, the pomegranate and the vine are quicker to mature than the palm, the cypress and the olive, which are rather dry than humid by nature. Wherefore we some times propagate figs in nurseries from cuttings rather than attempt to raise them from seed: unless there is no other way to secure them, as happens when one wishes to send or receive seed across the sea. For this purpose the ripe figs which we eat are strung together and when they have dried out are packed and s.h.i.+pped wheresoever we wish, and thereafter being planted in a nursery they germinate. In this way the Chian, the Chalcidian, the Lydian, the African and other foreign varieties of figs were imported into Italy.

For the same reason olives are usually propagated in nurseries from truncheons such as I have described, rather than from its seed, which is hard like a nut and slow to germinate.

_Of seeding alfalfa_

XLII. You should take care not to plant alfalfa[93] in soil which is either too dry or half wet,[94] but in good order. The authorities say that if the soil is in proper condition a _modius_ (peck) and a half of alfalfa seed will suffice to sow a _jugerum_ of land. This seed is sowed broad-cast on the land like gra.s.s and grain.

_Of seeding clover and cabbage_

XLIII. Snail clover (_cytisus_) and cabbage is sowed in beds well prepared and is transplanted from them and set out so that the plants are a foot and a half apart, also cuttings are taken from the stronger plants and set out like those which were raised from seed.

_Of seeding grain_

XLIV. The quant.i.ty of seed required for one _jugerum_ is, of beans, four modii, of wheat five modii, of barley six modii, and of spelt ten modii: in some places a little more or a little less; if the soil is rich, more; if it is thin, less. Wherefore you should observe how much it is the custom to sow in your locality in order that you may do what the region and the quality of the soil demands, which is the more necessary as the same amount of seed will yield in some localities ten for one, and in others fifteen for one, as in Etruria. In Italy also, in the region of Sybaris it is said that seed yields as much as one hundred for one, and as much is claimed for the soil of Syria at Gadara, and in Africa at Byzacium.[95]

It is also important to consider whether you will sow in land which is cropped every year which we call _restibilis_, or in fallow land (_vervactum_), which is [ploughed in the spring and so] allowed an interval of rest."

"In Olynthia," said Agrius, "they are said to crop the land every year but to get a greater yield every third year."

"A field ought to lie fallow every other year," said Stolo, "or at least be planted with some crop which makes less demand upon the soil."

3 CULTIVATING TIME

"Tell us," said Agrius, "about the third operation which relates to the cultivation and the nourishment of the crops."

_Of the conditions of plant growth_

"All things which germinate in the soil," replied Licinius, "in the soil also are nourished, come to maturity, conceive, are pregnant and in due time bear fruit or ear, so each fruit after its kind yields seed similar to that from which it is sprung. Thus if you pluck a blossom or a green pear from a pear tree, or the like from any other tree, nothing will grow again in that place during the same year, because a tree cannot have two periods of fruition in the same season.

They produce only as women bear children, when their time has come."

XLV. Barley usually sprouts in seven days after it has been sowed, and wheat not much later, while the legumes almost always sprout in four or five days, except the bean, which is somewhat later. Millet and sesame and the other similar grains sprout in the same time unless some thing in the nature of the soil or the weather r.e.t.a.r.ds them. If the locality is cold, those plants which are propagated in the nursery and are tender by nature ought to be protected from the frosts by coverings of leaves or straw, and, if rains follow, care should be taken that water is not permitted to stand any where about them, for ice is a poison to tender roots under ground, as to sprouts above, and prevents them from developing normally. In autumn and winter the roots develop more than does the leaf of the plant because they are nourished by the warmth of the roof of earth, while the leaf above is cut down by the frosty air. We can learn this by observation of the wild vegetation which grows without the intervention of man, for the roots grow more rapidly than that which springs from them, but only so far as they are actuated by the rays of the sun. There are two causes of the growth of roots, the vitality of the root itself by which nature drives it forward, and the quality of the soil which yields a pa.s.sage more easily in some conditions than in others.

_Of the mechanical action of plants_

XLVI. In their effect upon plants such natural forces as I have mentioned produce some curious mechanical results. Thus it is possible to determine the time of the year from the motion of the leaves of certain trees like the olive, the white poplar and the willow, for when the summer solstice has arrived their leaves turn over. Not less curious is the habit of that flower which is called the heliotrope, which in the morning looks upon the rising sun and, following its journey to its setting, never turns away its face.

_Of the protection of nurseries and meadows_

XLVII. Those plants, which, like olives and figs, are grown in the nursery from cuttings and are of a tender nature, should be protected by sheds built of two planks fastened at each end: moreover they should be weeded, and this should be done while the weeds are still young, for after they have become dry they offer resistance, and more readily break off in your hand than yield to your pull. On the other hand the gra.s.s which springs in the meadows and gives you hope of forage not only should not be rooted out while it is growing, but should not even be walked upon; hence both the flock and the herd should be excluded from the meadow at this time and even man himself should keep away, for gra.s.s disappears under the foot and the track soon becomes a path.

_Of the structure of a wheat plant_

XLVIII. A corn plant consists of a culm bearing at its head a spike, which, when it is not mutilated, has, as in barley and wheat, three parts, namely: the grain, the glume and the beard, not to speak of the sheath which contains the spike while it is being formed. The grain is that solid interior part of the spike, the glume is its hull and the beard those long thin needles which grow out of the glume. Thus as the glume is the pontifical robe of the grain, the beard is its apex. The beard and the grain are well known to almost every one, but the glume to very few: indeed I know only one book in which it is mentioned, the translation which Ennius made of the verses of Evhemerus. The etymology of the word _gluma_ seems to be from _glubere_, to strip, because the grain must be stripped from this hull: and by a like derivation the hull of the fig which we eat is called a glume. The beard we call _arista_ because it is the first part of the corn to dry (_arescere_), while we call the grain _granum_ from the fact that it is produced (_gerere_), for we plant corn to produce grain, not glumes or beards, just as vines are planted to produce grapes, not tendrils.

The spike, which, by tradition, the country people call _speca_, seems to get its name from _spes_, hope. For men plant with hope of the harvest. A spike which has no beard is called polled (_muticus_), for, when the spike is first forming, the beard, like the horns of a young animal, is not apparent but lies hid like a sword in its scabbard under a wrapping of foliage which hence is called the sheath. When the spike is mature its taper end above the grain is called the _frit_, while that below, where the spike joins the straw culm, is called the _urrunc.u.m_.

XLIX. When Stolo drew breath, no one asked any questions, and so, believing that enough had been said on the subject of the care of the growing crops, he resumed.

4 HARVEST TIME

"I will now speak about the gathering of the crops."

_Of the hay harvest_

And first of the meadows: when the gra.s.s ceases to grow and begins to dry out with the heat, then it should be cut with scythes and, as it begins to cure, turned with forks. When it is cured it should be tied in bales and hauled into the steading; then what hay was left lying should be raked together and stacked, and, finally, when this has all been done, the meadow should be gleaned, that is, gone over with the sickle to save what ever gra.s.s escaped the mowing, such as that left standing on tussocks. From this act of cutting (_sectare_) I think that the word _sicilire_ (to glean with a sickle) is derived.

_Of the wheat harvest_

L. The word harvest (_messis_) is properly used with respect to the ingathering of those crops which are reaped, and from this action (_metere_) its name is derived, but it is mostly used in respect of corn. There are three methods of harvesting corn, one as in Umbria, where they cradle the straw close to the earth and shock up the sheaves as they are cut: when a sufficient number of shocks has been made, they go over them again and cut each sheaf between the spikes and the straw, the spikes being thrown into baskets and sent off to the thres.h.i.+ng floor, while the straw is left in the field and stacked.
