Furnished hy Sir John Johnstone.* 
[Soil, clay, sand, and grit ; subsoil, clay and sand ; geological forma- 
tion, coal-grit of the middle oolite ; drained. After poor crop of 
turnips fed off. (The turnips were raised by 10 or 12 good cart-loads 
of short manure from the yard.) Sown broadcast in the middle of 
January, 1846; the crop appeared tolerable, but thin in patches; 
bagged August 22. Estimated yield 16 bushels per acre ; straw of 
middling strength ; grain good, 62 lbs. to the bushel.]t 
* The weight per bushel given for the specimens 13 to 2S, is not the result of actual 
weighings, but as near au approximation as Mr. Arkell's judgment would all'ord. 
f From a farm in llie occu])ation of Mr. Thomas Leadlay, Surgate-l)rows, Silpiio, 
N.R. of York. — For the careful collection and a full description of all tliose specimens 
we are much indebted to Mr. TurnbuU, the agent of Sir John Johnstone at Harkness.
