FARMER'S ASSISTANT. 409 



Mr. Forsyth makes mention of fifty walnut-trees, in, 

 England, being rented for fihy pounds sterling a year; and 

 that the Lessee cleared th.it amount from them, af er pay- 

 ing the rent. Most proba : > y, these were the shagbark 

 walnut. He directs that walnut-trees should be raised 

 from the nut, when fully ripe; that they will be fit to trans- 

 plant thi first Aummn after sowing; when they are to be 

 put inu beds, and transplanted every second year, until 

 they are lrge enough to'set out where they are to grow. 



Which management, he says, causes them to throw out 

 fine horizontal shoots, and brings them to a bearing state 

 much sooner, than when they make deep tap-roots; that, 

 when they are Ltrge enough to be trimed up to the height 

 of seven feet, they should be set out in the orchard, at the 

 distance of about six feet apan ; and, as they grow larger, 

 those found to be the best bearers are to be preserved, and 

 the rest cut away. In triming the trees, his composition is 

 to be applied (see FRUIT-TREES) and, previous to seting 

 them out, he directs that ine ground should be trench- 

 ploughed 



See TRENCH-PLOUGHING. 



The shagbaik walnut only is cultivated in England, and 

 this tree is no doubt the most valuable for its fruit, as it is 

 a more plentiful bearer than any other. Such land as 

 that on which it naturally grows is probably best for its 

 cultivation. 



WARMING OF ROOMS, fcc. As it is essential to 

 make a luile fuel answer for this purpose, as well as for 

 boiling, baking, roasting, Sec. we will here describe a cheap 

 and simple method for all these purposes ; leaving every 

 one to vary from it, by the use of stoves, or otherwise, as 

 he may think proper. 



Make, of sheet-iron, something in the shape of a potash 

 kettle, but not near so deep in proportion to its breadth on 

 the rim, and let it be, say, two and a half feet in diameter 

 across the rim; set r, bottom upward, on brick-work suita- 

 ble to the dimensions of the rim, about ten inches high, 

 leaving a place to fix an iron door, like the door of a com- 

 mon stove : Build a brick wall all round and over this, 

 leaving a space between it and the sheet-iron, of about two 

 inches, and an opening where the door, just mentioned, is 

 placed. Apertures are to be left in this outer wall, for in- 

 sening tubes for carrying off the air that is heated, between 

 the outer wall and the sheet-iron, into different apartments. 



When a fire is made within the part covered by the 

 sheet-iron, the air between that and the outer wall be- 

 comes rarified, and of course ascends through the tubes into 

 the different apartments or rooms, while the fresh air is
