PRACTICAL FARMER.

to come, allowing each tree set the year before, 

 by cuttings or layers, to produce five, and each 

 over that age, ten, which is infinitely short of what 

 can be effected, then the number of trees for the 

 fourth year will be 55,200, the fifth year, 372,200, 

 the sixth year, 2,500,200, and the seventh year, 

 15,872,200. 



But as these last numbers outstrip all practical 

 calculations within the bounds of reason, we will 

 therefore go back to the beginning of the fourth 

 year, which commences with 8,200 trees. 



As this number will extend beyond the conve- 

 nient limits of the nursery, of course it will begin 

 transplanting the trees to the place of their desti- 

 nation. To effect this, I would advise to hire a 

 piece of ground on a permanent lease, say twenty 

 acres, and more if can be done conveniently, with 

 the privilege of purchasing in three years. 



I would prepare a part of this field, and trans- 

 plant the 1,200 trees of one and two years old. 

 These I would set in rows eight feet and six inch- 

 es apart, and the trees in the row, a little short of 

 twenty inches, or ten trees in a rod, by which ar- 

 rangement an acre will contain 3,200 trees. The 

 whole field ought to be well fenced, or at any rate, 

 the trees protected from every kind of depreda- 

 tion. The trees three years old may he calculat- 

 ed to yield three pounds of leaves each ; those of 

 two years one and a half pounds ; and those of 

 one year half a pound ; in all, 4,600 pounds with- 

 out those set this year. These will feed 120,000 

 worms, which will yield fifty pounds of silk, which 

 at $5 per pound, will amouut to $250. 



The expenses and avails this year may bu set 

 down thus : 



Rent of nursery, $5 



Rent of field, twenty acres, at $2 per 



acre, 40 



Transplanting 1,200 trees, preparing 



ground, &c., 12 



Attendance of worms, and reeling 50 



pounds silk, 100 



$157 

 50 pounds of silk, at $5 per pound, 250 



Nett gain fourth year, $90 



FIFTH YEAR. 



The fifth year there will be 7000 trees two years 

 old, and of course, ready for transplanting, which, 

 with the 1,200 already transplanted, making 8,2C0, 

 will occ! py a little more than two and a half 

 acres. These, with those one year old, will pro- 

 duce leaves enough to feed something over a mil- 

 lion of worms, from which may be calculated on 

 416 pounds of silk.

It will be perceived that, as at the ratio at which 

 we j)roceeded thus far in propagating, there will 

 be this year untransplanted 47,000 trees of one 

 year's growth, and 317,(00 set this year; in all 

 364,000. These could not have room to stand 

 in the original acre of nursery; 1 shall therefore 

 suppose that the cultivator has, this year, either 

 enriched and prepared a part of the twenty acres, 

 in order to enlarge the nursery, or has procured a 

 sufiicient quantity of suitable ground elsewhere, 

 in which case the 3'et unoccupied portion of the 

 twenty acres may be considered an equivalent, 

 and the rent, therefore, need not come into the ac- 

 count. 



The sixth year will commence by transplanting 

 the 47,0( trees two years old this spring, which 

 with those transplanted before, will make 55,200,, 

 leaving space in the twenty acres for 8,800 iriore. 

 There will then be for this year's feeding 200 trees 

 of five years, 1,000 four years, 7,000 of three years, 

 and 47,000 of two years. These will |)roduce at 

 least sixty thousand pounds of leaves, which, with 

 what may be gathered from two hundred and 

 twentythree thousand of one year old, will amount 

 to one hundred thousand pounds, which will feed, 

 at a reduced calculation, two million five hundred 

 thousand worms, which number will make ten 

 hundred and forty one pounds of silk, worth 

 $5265.

At the season of the commencing this spring, 

 the silk made the year before will have been sold, 

 and after |;aying all expenses of the season, will 

 have left a net gain of above three thousand dol- 

 lars ; and as there will be three hundred and stren- 

 teen thousand trees of two years old, if one half 

 of them are sold at two cents each, (the purchaser 

 being at the expense of removing them.) which
