298 SUMMER FROSTS AND THEIR EFFECTS, ETC. 



although this disadvantage applies to the eastern counties 

 generally. The western counties are much more favoured in 

 this respect. It is on the west, south-west, and south of 

 Britain that all the early potato growing districts are to be 

 found, an essential condition of which is freedom from these 

 as well as spring frosts. As illustrating the mildness of our 

 west coast climate, it may be stated that the minimum air 

 temperature recorded for 1904 at Scilly was 33° F., and at 

 Pembroke 30° F. 



It will be interesting to note in conclusion that in Scotland 

 swedes and turnips constitute almost entirely the root crop, 

 the acreage of mangels being very small, whereas in France 

 it is the latter only which practically form the root crop, 

 swedes and turnips being grown to a very small extent 

 in that country.
