226 APPENDIX. [March, 



er. The leaves, although not so large as the original tree produces, 

 are larger than any other kind I have seen ; and I think will produce as 

 much weight per acre as the parent tree. They appear to be much 

 more hardy, some of them have stood out without protection the three 

 past winters without being injured. I would state, however, that the 

 severe frost we had last fall killed the tops of many of the young trees, 

 the bark on the bodies of the trees being started, while the tops were 

 uninjured. The roots were not hurt, and have stood the past winter 

 without further damage. Those trees that have not been taken up the 

 two last years, are nearly large enough to produce seed ; and I expect 

 the next generation will be as hardy as our native trees. The two 

 trees that produced the seed were killed in the winter of 1835, one en- 

 tirely, the other all but the root. The latter started many sprouts, 

 which I have multiplied by laying them in. I am preparing to set one 

 acre this spring, in order to remain. If the tops should be destroyed 

 the first year, I feel confident the roots will not be, and I have not had 

 them hurt after the first year. I have the Canton mulberry, which 

 was grown from seed obtained at Northampton. I have found them 

 quite as tender as the Multicaulis. 



I have made selections from the white mulberry, which I think are 

 valuable, and by engrafting on the more ordinary trees, much improve- 

 ment can be made. I engrafted some last spring with my seedlings, 

 and from the selected white mulberry ; both kinds grew well, and have 

 not been injured by the past winter, excepting being somewhat broken 

 by the snow. 



I have tried the various kinds, except the Alpine and Broussa, for 

 feeding the worms, and do not perceive any difference in the worms, as 

 it respects their growth, or health. I have but one objection to the 

 Multicaulis, and that is, they do not come forward soon enough to be 

 depended upon in all cases. I think, in order to raise silk to the most 

 profit, we want some kind that has a large leaf, and that is hardy, to 

 commence with, as early as the fore part of June, and take the Multi- 

 caulis for the last crop. I have found that the worms that were fed 

 early in the season, have produced the heaviest cocoons, the first 

 weighed some over 4 lbs. per 1000, while those that wound up as late 

 as the 10th of September were but about one half as heavy. They 

 ought to finish their labor at least as soon as the first of September; 

 they will then generally escape the cold storms, which are essentially 

 injurious to the worms."
