of trees, or other rubbifh ; then the bed earth that can be had, and on that dung, oneload of fixteen feet to four trees; this is covered with more good earth, and this levelsthe hole with the reft of the field ; then prune the roots and plant, fetting a pole by theyoung tree to the north, and a fpur poft on the other fide, to guard it from the plough.Twine no ft raw the firft year, becaufe of the infed forjicula aitricularia , L.; but inNovember bind ft raw around them againft the cold, or, as ftraw is dear, the poa rubra,which abounds. Never, or very rarely, water. Much attention to remove all budsnot tending in the right diredion.
The fourth fpring after planting, their heads are pollarded in March, leaving the{hoots nine inches long of new wood, and feeking to give them the hollow form of acup, and that the new buds may afterwards divide into two or three branches, but notmore. The next year they begin to pluck the leaves. They are attentive in pruning,which is done every fecond year, to preierve as much as they can the cup form, as theleaves are gathered the more eafily. Thus it is about fourteen years from the feed be-fore the return begins.
After gathering the leaves, a man examines and cuts away all wounded flioots ; andif hail damage them, they are cut, let it be at what time of the year it may. Old treesare pruned after gathering, but young ones in March. In autumn, the leaves are nevertaken for cattle before the i ith of November, as the trees after that time do not fuffer.The third year after planting young trees, they fow about a hat-full of lupines aroundthe ftem, and when about ten inches high, dig them in for manure. The opinion hereis, that the mulberry does very little harm to rye or wheat, except that when cut thefalling of branches and trampling are fomewhat injurious. Maiz, millet, and panic aremuch more hurt. A tree, five years after tranl'planting, gives ten pounds of leaves,each twenty-eight ounces. At ten years, eighteen pounds. At fifteen years, twenty-fivepounds. At twenty years, thirty pounds. At thirty years, fifty pounds. At fifty tofeventy years, feventy pounds. There are trees that give eighty pounds, and even onehundred pounds. The price of leaves is commonly 4 livres per one hundred pounds(twenty-eight ounces). For one ounce of grain five hundred pounds of leaves arenecelfary, and yield feventeen pounds of cocoons ; but among the rifings in the moun-tain of Brianza, twenty-five pounds. To make a pound of filk, of twelve ounces, fivepounds or fix pounds of cocoons, of twenty-eight ounces, are required. Price of co-coons, in the low watered country, 2 livres per pound (twenty-eight ounces). AtMozzata, 2f livres. At Brianza, 3 livres. The grain is hatched in a chamber, heatedby a chimney, and not a ftove, to feventeen degrees of Reaumur (feventy and a halfFar.) ; but before being placed in this chamber, they are kept eight days under a bed,with a coverlet upon them, in boxes covered with paper pierced ; and when hatched laythe young leaflets of the mulberries on the paper, to entice them out. The method ofconducting the bufinefs here is the fame as in France , the landlord furnilhes half thegrain, and the peafants half, and they divide the cocoons. Price of grain, 2 livres theounce. Mulberries, of all ages, are pollarded every fecond year ; a mifchievous cuf-tom, which makes the trees decay, and leffens their produce; it is never done in Dau-phine, where the culture is fo well underftood.
Milan . —Sig. Felice Soave made fome interefting trials on filk worms.
At Lambrate, near Milan , two ounces of feed in rooms kept to the heat of twenty, threeand twenty-four degrees of Reaumur, hatched well, and kept healthy : the 28th of Aprilthe feed was placed in the rooms, and hatched in the third, fourth, and fifth day : the21 ft of May the firft cocoon feen, and at the end of the month all were at work.
