Specimen No. 96. — Scotch Purple-top Bullocks Turnip. 



From Sir J. Johnstone, Bart. 



\_Soil, free hazel loam ; subsoil, gravel ; geological formation, the Ox- 

 ford clay, but here covered up with calcareous rubble from above ; 

 undrained. Previous crop wheat (heavy straw, much laid ; very poor 

 crop of grain). Turnips manured with 6 loads of good rotten farm- 

 yard dung, and about 3 cwt. guano and 20 bushels of ashes. Drilled 

 middle of June ; very even good crop for the district. Collected No- 

 vember 21st.] 



Estimated produce, in bulbs, 15 tons.* 



5, in tops, 2 tons, 13 cwt. 



In this atid the following specimens the numbers given for the crop must be con- 

 siileved only as an approximation. This crop of turnips, it is said, "would carry 200 

 liogs for a week per acre."' In calculating tlje produce, it lias been assumed {hat a 

 hog will eat 24 lbs. of turnijis ])er diem (see Stephens' 'Book of tiie Farm,' vol. ii. 

 ]). 18) ; but of course any such calculation must be attended with much uncertainty. 

 VV^e liave, however, preferred giving these data rather than none at all, but it is not 

 I roposed to use tliem as the basis of any argument.
