mixture of seed of three different and successive 

 years growth. As the latest growth will al- 

 ways spring first, the different proportions of 

 the mixture will rise at different times. The 

 fly will naturally fasten on that which first ap- 

 pears ; but so soon as a second growth comes up, 

 it will quit the first, and attack this ; and the 

 same preference will be given to the third when 

 it appears, the youngest being always the sweet- 

 est and most palatable. But before this last is 

 finimed, what remained of the two former 

 growths, will be so far advanced, and have ac- 

 quired such a harsh and bitter taste, that the fly 

 will not return to them again ; and thus a suffi- 

 cient quantity of plants will escape, and remain 

 for the crop. As this is a very easy method, it 

 is surely worth while to make the trial. 



4//7, Produce, Of turnip, in drills from 2-~ 

 to 3 feet wide, when the soil is good, the season 

 favourable, and the management proper, an acre 

 will yield from 50 to 60 tons. But as turnips 

 are not infrequently raised on land rather cold 

 and wettish ; and as the mode of culture is not 

 yet, perhaps, universally well understood, the 

 average produce cannot be calculated above 35 

 ton per Scots acre, 



7/, Consumption. The turnips are generally 

 carted from the field to the house or cattle sheds, 

 and used for fattening cattle, or for feeding milk 

 cows, and young stock. Fed off this way, they 

 produce a great quantity of manure. Seldom 

 are sheep fed here with turnip, at least to any 

 considerable extent. The chief inconvenience 

 attending this crop, is the labour of carting them 

 from the field, and in wet weather or moist land, 

 the poaching and spoiling the ground. To prevent
