e On Swedes, an application of 3 cwt. per acre gave Mr Hax- 

 ton, in Fifeshire, an increase of 1 ton upon a crop of 17^ tons ; to 

 Mr Bourhill, in Mid-Lothian, an increase of 14 cwts. on a crop of 

 13 tons ; and, to Mr M'Lintock, of 32 cwt. on a crop of 10 tons. 

 On the whole, therefore, the applications to turnips hitherto 

 published can scarcely be said to have done any sensible good 

 when the application of farm-yard manure was sufficiently large. 

 6. On grass and clover cut for hay, numerous experiments 

 have been tried, though none with that attention to careful 

 duplicate trials which would justify us in drawing positive con- 

 clusions. I have brought together a number of the most trust- 

 worthy of these in the following table :
