Average product of an

per 



Our own calculation is predicated upon the 

 statement of Mr. Smith, that a full grown tree 

 will yield foliage enough for 5,000 worms, and 

 as 108 trees at 20 feet square apart will stand on 

 an acre, so will that number of trees support 

 540,000 worms, and as 3,000 will make a pound 

 of silk, so will 540,000 make 180 Ibs., as per 

 example: 



108 No. of trees on an acre, 



5000 No. of worms which one full 



grown tree will support, 



8,000) 540,000 



180 Ibs. of silk raised from an acre, 

 4 



^720 the gross value of an acre. 



We will now state an account current, by 

 which the nett profit of an acre will be clearly 

 demonstrated, and we beg leave to make this ex- 

 planation, that, with a view of providing against 

 all possible contingencies, we have taxed 540,- 

 000 worms with the expense of the labor of 

 1,000,000, which will more than cover all draw- 

 backs arising from mortality among the worms, or 

 any other unforseen casualties.

Having thus demonstrated the practicability of 

 realizing $565 80 cents, from one acre in the 

 silk culture, well attended to, on which, howe- 

 ver, an excess of labor equal to 46 per cent., o r 

 on which the cost of the labor necessary for 

 1,000,000 is charged upon 540,000 worms,we will 

 now prepare a table, shewing the nett profits on 

 from 1 to 10 acres, the same excess of labor 

 being charged, the object of which, is, to cof er 

 any contingent demands which may be made 

 upon the product of the worms, whether by 

 mortality or otherwise.
