wards, and thereby keep them warm during the greater part 

 of the night. In the second place, there is no mention made 

 of the frosts and cold damps of spring and autumn, which 

 must of necessity fall more on a wall that is sloped than on 

 one which is perpendicular ; and I think he will find that in 

 the spring he will have the shoots and blossom forced by day, 

 and destroyed by night; and in the autumn the first frost that 

 comes will fall so sharp on the leaves and fruit, as to destroy 

 the former, and, consequently, render the other useless. In- 

 dependent of all this, the rain, as it falls, will be collected in 

 the same way as on the roof of a house, which will both have 

 a tendency to destroy the wall and injure the roots of the trees.

J. A. B. Esq.'s first advantage, he says, is the exposure to 

 the sun. Perhaps he does not consider the exposure of the 

 blossoms of his trees to frosts, hail-storms, &c. more than if 

 the trees were on a perpendicular wall. Next, he says, his 

 hollow wall will be drier ! How ? By being more exposed to 

 falling rains, &c. ? But the effect of these he proposes to dry 

 by fires, which, if made strong enough for that purpose, would 

 be strong enough to damage the trees planted within. He 

 says dung may be fermented there also : I think not to advan- 

 tage. What man could use a fork in that space ? Besides, 

 the dung would be better worked in the open air. If there 

 be any walls in his neighbourhood with buttresses to them, 

 Jet him examine the face of those buttresses, and see if they 

 be drier than the walls they are built to support. I have 

 seen walls but a few inches out of the perpendicular, which I 

 could not keep clean from moss. Fruit would be liable to rot 

 by being in contact with a wall so constructed.

Dear Sir, 

 Full of the resolution which I had formed last week, of 

 becoming an author, I have bought a quire of paper, a bottle 

 of Japan ink, and a quarter of a hundred of quills, as extra 

 stock for that purpose, and I intend dedicating the whole to 

 you in the course of this winter. I felt greatly encouraged by
