AN EXTENSIVE PIGGERY.

From the Farmers Monthly Visiter. We visited one establishment near the Spy pond in West Cambrige which will be thought remarkable; it was on ground very near the precise spot where, in company with a grandmother and some elder female cousins, at the early age of five or six years, all of us got lost and wandered in terror late in the afternoon, in a swamp of the high blue-berry bushes. It is now a place for hogs, where no less than nine hundred of these animals, from the smallest size to the lusty twoyear-old weighing eight hundred to a thousand pounds, are kept. And how will the reader suppose so many devourers could be sustained pent up in a pen of not more than one or two aeres, without starving? It is in this wise:-Some five or six years ago the proprietor of this hog establishment engaged to pay the municipality of the city of Boston twenty-five hundred dollars a year for the delivery on the spot of the offal collected from the kitchens of the several families in the city who had not other means of disposing of it. This offal was fed out daily to as many swine as it would keep. The first contract of two or more years turned out to be of great profit to the pro

The pine plains supplied with this manure-the steri ground that formerly produced little or nothingyields such crops of rich garden vegetables as no one previously acquainted with them ever dreamed he should there see grow.

Among the practical operators on the land in West Cambridge, without asking of them we take the liberty to use a few names, not because others may not be their equals, but because they happen to have fallen more particularly under our observation at the time of our recent visit.

PENNSYLVANIA FARMING.

For the Farmers' Register. In the months of August and September, I was several weeks in Pennsylvania, and passed through several counties, east of the north mountain; having no speculation in view, either in lands, or mulberries, I was studious in examining the character of the soil, and the course and method of ther cultivation. The lands in all the counties I was in, are naturally fertile, with the exception of Adams; they vary, as with us, in quality, in the same neighborhoods, though they have been much equal

Indian corn. They will not have this year a full crop of Indian corn, in consequence of the cool summer, which will occasion no diminution here. Our wheat, unless thrashed out early, is sometimes greatly injured by the weevil fly; they can keep theirs in the straw 'till winter without danger. By a heavy drought in mid-summer, our grass suffers most, but it springs earlier and grows later. In the marl region, we can apply calcareous makiln costs ten cents per bushel; and to those who have the stone on their own farms, preparing it is equal to eight. Their expenses on agricultural implements greatly exceed ours; on account of the stone which pervades the country, they require to be much heavier than ours, and soon wear out; their horses cannot plough a day without shoes. A farmer who held a farm of one hundred and seventy acres, told me his blacksmith's bill exceeds annually $100. In fruit and vegetables our advantages are decided, they can grow none which do not succeed here. On the west side of the Delaware, except in very favorable situations, those who indulge in the luxury of peaches, water-melons, and sweet potatoes, get them from the city. With regard to manual labor, I could form no decided opinion. The wages there are very high but they can call on laborers at pleasure, and discharge them when the work is done. Many of the readers of the Register can estimate the yearly cost of a large family of domestic slaves, who are treated with kindness and humanity. The rotation of crops is a matter unsettled in They have eaten out many a fair estate; and Maryland and Virginia, and I was desirous to as-think there was more correctness in the apothegm certain the most approved in Pennsylvania, but found they had no regular system; so long as a field produces a good crop of grass, they are reluctant to break it.

During the past four years I have watched with deep interest the progress of the silk culture in our country; and actuated, I trust, by a sincere desire to awaken an interest in the community in regard to a branch of business, by which I verily believe thousands in our land might acquire an honorable and comfortable subsistence, I have labored to test both the practicability and profit of the culture of silk. Last year my experiment went no farther than the production of the cocoons-farm bag, and this was hung to a beam in the cel and though the results were highly encouraging, lar.

The soil on which my trees were grown is a heavy clay-three or four years ago, the land would not have produced 20 bushels of corn to the acre. The two previous seasons, the lot on which my experiment was made had been very moderately manured-the present season it was covered with what might be considered a good coat of marl and barn-yard manure mixed.

The 20th to the 23d of April last, I planted a half acre lot with morus multicaulis roots, cuttings,

eggs which has succeeded so well with me, because so much disappointment has been experienced in regard to eggs. Other modes equally good may douptless be adopted for retarding the eggs; the above plan, however, succeeded with me to admi ration; the last hatching the 27th of August, was as perfect as the first. This year I saved my eggs with even greater care than last, and am preserving them in the same way; and I cannot but recommend others to preserve them as above, unless they have actually tried some other mode which has proved equally good.

July 18th, I hatched some two or three thousand mammoth white. July 26, five or six thousand sulphur. July 31, two or three thousand sulphur. August 19th, over 20,000 sulphur-and August 27th, hatched the last, say 5 to 8,000, sulphur. The mammoth white worms wound in 24 to 28 days the sulphur 28 to 33 days.

The top was eut of within two inches of the root, and the roots were laid horizontally in the row, about ten inches apart.

Another objection is the difficulty of one lb. of cocoons, and a greater weight of cocoons preventing the worms from winding under the necessary to make one lb. of reeled silk, than the hurdles, and around them among the litter.

supposed the great mass of persons engaging in the silk business would feed. I was often obliged to feed wet leaves, owing to the frequent long storms, and the worms appeared to experience no injury whatever from this. Still I did not consider it safe to feed leaves gathered in the storm, and dripping wet; and in our attempts to dry the leaves, some became wilted and were thrown away. The worms also were always abundantly fed, and a partial waste of leaves frequently no doubt occurred in this way. These things, together with the loss of perhaps the value of near one lb. of reeled silk, by worms falling from the shelves, would vary the result a little, and might show that 190 lbs. of leaves would produce one lb. of reeled silk.

I do not doubt, but that under the most favorable circumstances a few lbs. of cocoons might be produced on 10 or 12 lbs. of leaves to the lb. of cocoons. Nor do I doubt that one lb. of reeled silk may be produced from 8 lbs. of cocoons, or even less. Much depends on the quality of the cocoons, and more on the time when they are weighed, whether in a fresh and green, or entirely dry state. I could have selected from my lot, even in a fresh state, 8 lbs. of cocoons, which would, beyond all question, have produced one lb. of reeled silk-but this would be no test of the profit of the business. The public do not wish to know so much the very maximum that can be made, as what may be regarded an ordinary standard for every prudent farmer-and I am now perfectly, persuaded, from two years experienced that I am not greatly mistaken.

Last year I produced at the rate of 510 lbs. of cocoons to the acre-this year I produced at the rate of 520-and my deliberate opinion is, that more will fall below this standard than will exceed it—and in one case, where a less quantity of leaves will give the above quantity of silk, two cases will decur that will require a greater.

seeing realized.

reeled silk the first year-or because the 120th part of an acre will produce so much—then a plantation of ten hundred and twenty acres will produce so much. I am pleased to see experiments made with all the accuracy imaginable, even on the smallest scale-good may result from them-but they are no safe guide for the practical man who is about to embark in a new business. I regard that experiment in this stage of the silk culture in our country, as valuable, when it is made from a lot sufficiently large-when this lot is in an average state of cultivation, and when the cocoons may be considered of an average quality. Then, if this shows a reasonable profit, it will accomplish more than whole volumes of calculation, or numberless very small experiments. The quantity of land named by the committee I regard as sufficiently small for any satisfactory results-and should they continue the liberal policy of offering premiums the following year, I would respectfully suggest whe ther the quantity of land from which the experiment is made, ought not to be increased.

But to recur to the matter of profit. The above shews us 48 lbs. of reeled silk, 16 oz. to the lb. as the product of an acre. If this is worth, as I understand it now is, $6 per lb. then the gross proceeds of an acre will be $288. The first year, let it be remembered. Or if it should be worth but $4.50 per lb. which is undoubtedly the safest price at which to rate it, the gross proceeds of an acre will then be $216.

In regard to the cost of production, it is confi dently asserted by many, that it can be produced for $2 per 1b. Mine cost me much more than this. My experience, however, satisfies me that it can be produced for $2.25 per lb. and I incline to the belief that it may be produced for $2. Produced on the farm in a small way, the cost will be next to nothing-the whole product will be clear gain. Now take the product of an acre as above Most happy will I be, and greatly will it be for stated, at $288, and allow this to be made at an the interest of the community, if it shall be found expense of $2 per lb. you have a net profit of $192 on farther experience that 80 or 100 lbs. of leaves per acre!! Allow the cost of production to be will make one lb. of reeled silk instead of 214 or $2.25, and you still have a net profit of $180. 215, as required in my experiment, for my quarter Again-take the product at $216, (allowing the of an acre did produce 2,576 lbs. of leaves, and the silk to be worth only $4.50 per lb.) and let the trees were not stripped remarkably close either-cost of production be 82, it gives a net profit of then the amount of reeled silk per acre would be $120 per acre; but allow the cost of production to the handsome yield of 104 to 128 lbs!! A result, be $2.25 per lb.-the sum at which I know it can albeit, which I frankly state, I utterly despair of he made--and it still affords us a net profit of $108.
