TARES, AND TURNIPS. Ill 



4. On mixed tares and beans cut green, three experiments, 

 made in 1843, gave respectively 



a Mr Fullarton, Forfarshire 



No dressing, 88 cwt. 



Sulphate of soda, 3 cwt. . . . 91^ ... 



b Mr McClelland, Wigtonshire 



No application, ... . 96 cwt. per imperial acre. 



Sulphate of soda, 3 cwt. . 107 ... 



c Mr M'Lintock, Lanarkshire 



No application, . . . . . 1 36 cwt. 

 Sulphate of soda, 2 cwt. . . . 200 ... 



In all there was an increase, though only in the last was it so 

 decided as, in the absence of double experiments, to satisfy us 

 of its economical value. 



5. On turnips , various experiments were made in 1843 

 with sulphate of soda applied alone, either along with the 

 home manure, or as a top-dressing to the young plants. 



a On the purple-topped yellow variety, by Mr Melvin, Mid- 

 Lothian, the sulphate applied with the manure in the drills 

 gave, per imperial acre 



Farm-yard manure, 20 tons, gave 21 tons 10 cwt. of bulbs. 



Do. do. 20 tons, T 



Sulphate of soda, 2^ cwt. j 

 Farm-yard manure, 20 tons, 1 -,_ .. 



Sulphate of soda, 3 cwt. j 



With two results so contradictory as these, we cannot ven- 

 ture to say that in this case it did any good. 



b On Dale's hybrid, by Mr Proudfoot, Mid-Lothian 



Farm-yard manure, 28 tons, gave 14 tons 16 cwt. of bulbs. 



Do. do. 28 tons. 



Sulphate of soda, 2J cwt. 



Another experiment on the same variety, by Mr McClelland, 

 in Wigtonshire, also gave no difference in the result. But one, 

 made by Mr M'Lintock, on a field of light sandy loam in poor 

 condition, gave from
