120 AGRICULTURAL REPORT. [March, 



son. This is a degree of despatch and facility in the produc- 

 tion of silk highly encouraging. I will remark here likewise, 

 that the roots of these trees, set out in the spring, have pro- 

 duced foliage much earlier than has been obtained from roots, 

 whose shoots were cut off in the fall, and they left in the 

 ground, in those cases where they have survived the winter. 

 In the management above spoken of, the intervals between 

 the rows may be three to four feet, and the trees when laid 

 down in the furrow may be placed so that the top of one may 

 extend to the root of the other ; or perhaps it may be more 

 proper to say that they may be laid at full length in the fur- 

 rows in close succession. Under such circumstances, we may 

 avail ourselves with great advantage of these extraordinarily 

 valuable mulberries, both the Canton and the Perottet. The 

 Canton may be propagated as the Perottet, by layers and cut- 

 tings ; and the seed is procured without difficulty. The seed 

 of the Perottet, which is a hybrid plant, is not to be depended 

 upon to produce its like. Calvin Haskell, of Harvard, Mass., 

 who has an experience of several years both in the growing of 

 trees and the production and manufacture of silk, had two 

 plants of the Perottet mulberry from among the first, which 

 were brought into the country. From the seed of one of these 

 trees, he has produced trees, which give a leaf not so large as 

 the parent tree, but of large size, abundant, and excellent for 

 the feeding of worms. These Multicaulis seedlings, as he de- 

 nominates them, after being housed the first winter, endure 

 the climate, are easily propagated, and yield abundantly. I 

 shall give in the appendix some extracts of Mr. Haskell's letter, 

 fully explaining his management.* 



From the best information that I can obtain, the Perottet 

 mulberry can be expected to become acclimated only by grow- 

 ing it in high and dry situations, by avoiding to force its 

 growth with too liberal manuring, and especially by preventing 

 any water settling upon its roots. It is not safe to expose 

 any seedling mulberries, certainly those of the tender varieties,
