Experiments made by Mr. Young, Highfield, St. Quivox. 



The field on which these experiments were made is situated 

 about two miles from the Frith of Clyde, at a height of about 

 70 feet above the sea level. The land is light, with a sandy 

 subsoil. The crops since 1858 have been, two years pasture, 

 oats, potatoes, barley, pasture, oats, turnips. 



The plots were six drills wide, and were arranged in one 

 long line down the field in the following order : — N (1), 1, 6, 2, 

 7, 3, 8 ; H (2), 4, 9, 5, 10, 6, 11 ; N (3), 1, 8, 2, 9, 3 ;,N (4), 10, 

 4, 11, 5, N (5). The crop was sown on the 13th June, the land 

 being in excellent order and sufficiently damp to braird the 

 seed, which came away on tho 19th. On the 21st the plants 

 were attacked by the ily and much eaten. On the 18th July 

 the crop was thinned eleveu inches apart, and the plants were 

 good except on the Nothing plots, both No. 10, and one No. 11. 

 On the 3d August the crop was cleaned with the hoe, and some 

 plots still looked ill. 



The plants were weighed on the 29th November, and were 

 found to be all sound, but the number of the different plots 

 varied very much — so much so indeed that some of them ad- 

 mit of no satisfactory comparison. The unfavourable nature of 

 the weather may be best judged of from the table of the rainfall 

 obtained from a rain-guage on the field which Mr. Young 

 has supplied — 



The details of the experiments are contained in Tables XIX. 

 and XX.
