Mackenzie’s Plan.—“Work the ground until it is completely reduced and free from root weeds. Three plowings, with frequent harrowings and rollings, are necessary in both cases, before the land is in a suitable condition. When this is accomplished, form the drills; place the manure in the drills, plant above it, reverse the drills for covering it and the seed, then harrow the drills in length.
“It is not advantageous to cut the seed into small slips; for the strength of the stem at the outset depends in direct proportion to the vigor and power of the seed-plant. The seed-plant, therefore, ought to be large, rarely smaller than the fourth part of the potato; and if the seed is of small size, one half of the potato may be profitably used. At all events, rather err in giving over large seed than in making it too small; because, by the first error, no great loss can ever be sustained; whereas, by the other, a feeble and late crop may be the consequence. When the seed is properly
cut, it requires from ten to twelve hundred weight of potatoes, from 12½ to 15 bushels, where the rows are at 27 inches distance; but this generally depends greatly upon the size of the potatoes used; if they are large a greater weight may be required; but the extra quality will be abundantly repaid by the superiority of the crop, which large seed usually produces. Plant early in May.”
Barnum’s Plan.—“Plow deep and pulverize well by thoroughly harrowing; manure with compost, decomposed vegetables or barnyard manure; the latter preferable. When coarse or raw manure is used it must be spread and plowed in immediately. Stiff clay soil should always be plowed the fall previous. Lay your land in drills 27 inches apart, with a small plow, calculated for turning a deep, narrow furrow running north and south; lay on the bottom of the drills 2 inches of well-rotted barnyard manure, or its equivalent, then drop your potatoes, if of the common size, or what is more important, if they retain the usual quantity of eyes—if more, they should be cut to prevent too many stalks shooting up together; put a single potato in the drills or trenches 10 inches apart, the first should remain uncovered until the second one is deposited, to place them diagonally in the drills, which will afford more space between the potatoes one way, than if laid at right angles in the rows. The covering may be performed with a hoe, first hauling in the furrow raised on each side the drill, then carefully take from the centre of the space the soil to finish the covering to the depth of 3½ or 4 inches; by taking the earth from the centre of the space on either side to the width of 3 inches, it will leave a drain of 6 inches in the centre of the space and a hill of 14 inches in width gently descending from the drill to the drain, the width and depth of the drill will be sufficient to protect the plant against any injurious effects of a scorching sun or drenching rain. The drains in the centre will at all times be found sufficient to pass off the surplus water.
“When the plant makes its appearance above the surface, the following mixture may be used: for each acre take 1 bushel of plaster and 2 bushels of good ashes, and sow it broadcast as even as possible; a moist day is preferable for this operation—for want of it, a still evening will do.
“The operation of hilling should be performed once and once only during the season; if repeated after the potatoe is formed it will cause young shoots to spring up, which retards the growth of the potatoe and diminishes its size. If weeds spring up at any time they should be kept down by the hand or hoe, which can be done without disturbing the growth of the stalk.
“My manner of hoeing or hilling is not to haul in the earth from the space between the hills or rows, but to bring on fresh earth sufficient to raise the hill around the plant 1½ or 2 inches; in a wet season the lesser quantity will be sufficient, in a dry one the larger will not be found too much. The substance for this purpose may consist of the scrapings of ditches or filthy streets, or the earth from a barnyard that requires levelling: where convenient, it may be taken from swamps, marshes, the beds and banks of rivers or small sluggish streams at low water. If planted on a clay soil, fresh loam taken at any depth from the surface, even if it partakes largely of fine sand, will be found an excellent top-dressing. If planted on a loamy soil, the earth taken from clay pits, clay or slaty soil will answer a valuable purpose; in fact, there are but few farms in the country but what may be furnished with some suitable substance for top-dressing, if sought for. The hoeing and hilling may be performed with facility by the aid of a horse and cart, the horse travelling in the centre of a space between the drills, the cart-wheels occupying the two adjoining ones, thereby avoiding any disturbance or injury to the growing plants.”
Mr. Barnum’s method has attracted great attention, from the fact that he actually raised from 1,000 to 1,500 bushels
of potatoes to the acre! When this was first published it was received with great incredulity; calls were made for the method of cultivation, which drew forth an elaborate article from Mr. B., of which the above is but a morsel. It afterward was stated, and the most authentic and unquestionable evidence adduced in proof, that Mr. Barnum raised, upon experiment, at the rate of more than 3,000 bushels to the acre. Now, although the labor and the great amount of seed required would prevent the cultivation of many acres of land thus, yet it is worth a trial in a small way; and if one acre can be made to produce 1,000 bushels, it will be as much as is usually dug from five acres; and it is questionable whether the labor and seed for five acres are not more than that required by Mr. B.’s method for one.
Mr. A. Robinson’s Plan.—He says: “If I plant low ground, I plow my ground in beds in a different direction for the water to drain off, then harrow lengthwise of the furrows and small lands; having a number of them, side and side, I take a light, sharp horse-harrow, and harrow crosswise of the beds, which pulverizes the ground and fits it well for planting, leaving a small space between the rows, which answers for two purposes, one for a guide for the rows for dropping: this is done by dropping in the middle of the tracks of the harrow, which is easily and correctly performed, by any small boy. It also serves completely to fill up all cracks or holes, the seed lying fair and easy. I then drop my manure directly over the seed potatoes, and when covered up, the seed is safe from inundation, by being some inches above the surrounding surface: the seed lies warm under this manure, the rains drain into the middle furrows; I plant three feet distance; it takes the most of the surface that is pulverized to cover the potatoes, and by the time they are twice well hoed, my hills are as I want them to be. They naturally rise high above the surface in the form of a sugar-loaf: this hill is to turn off heavy rains,
