No. 4. Sulphate of soda and ivater, same proportion as No. 1. 
Sept. 1842. Shoot 1 inch, scarcely any difference ob- 
servable. 
April\BA4i. Weak shoots, but better than anything 
around it, and alive at to]). 
Nos. 5 and 6. Sulphate of soda sewn dry, same proportion as No. 1. 
Sept. 1842. Shoots from 3 to 4 inches long, of a good 
colour, and apparently more healthy than any 
around them. 
April ] 844. No. 5 recovering and gaining strength. 
No. 6 quite recovered and healthy; all around it 
dead. 
No. 7. The surface broken around the tree, and a mi.\ture of 
bones and earth applied at the rate of 8 quarters of 
bones to 22 loads of earth per acre. 
Sept. 1842. But little effect; shoots 1^ inch; not 
good colour. 
April 1844. Recovered, but not very strong. 
No. 8. With lime mixed iu the soil at the rate of about 
300 Winchester bushels per acre. The surface

Nos. 9 and 10. Watered ivith Ammoniacal liquor at the rate of 8 
gallons to 50 gallons of water. 
Sept. 1842. Shoots generally 1^ inch ; thin of foliage, 
but tolerably coloured. 
April 1844. No change on either. 
The manures were severally applied early in March, 1842, and re- 
peated in 1843. 
I draw no inferences from these experiments, except the following : — 
That liquid manures pass off, and leave no permanent effect. 
That various dry substances affected the broken constitutions of the 
plants in different degrees. 
That dry sulphate of soda (Nos. 5 and 6), is the specific remedy 
suited to the case. 
I am, my dear Sir,
