so well there. Hay with us is no doubt more bulky than 

 with them, but they usually have very much better weather for 

 making it, and in consequence it is generally superior to ours. 

 The reverse happens in regard to straw, as owing to our cooler 

 summers, our oat straw is much more palatable than theirs. 

 It should also be kept in view, in criticising the foregoing figures 

 from any point of view, that owing to the longer period over 

 which the Danish milk records have extended and the greater 

 number of cows embraced in them, the Danish figures are 

 likely to be more reliable than ours. 



Owing to proximity to, or distance from markets, every 

 country has districts where high prices prevail, and others 

 where they are low. For equal quality the feeding value of an 

 article of home growth is the same in all these districts, so that 

 the Danish system of calculating the cost by food equivalents 

 is a much easier and more satisfactory one than is ever possible 

 by putting a separate money value on each food. In the 

 south-west of Scotland bean meal is the concentrated food 

 most largely in use, and if it were taken as a basis and feeding 

 equivalents agreed on for the other substances, comparisons 

 between districts would be much more reliable than they are at 

 present. 



CHERRY LEAF SCORCH. 

 E. S. Salmon, F.L.S. 



{Mycologist to the South Eastern Agricultttral College, Wye, Kent). 



About 1900 the fungus disease known as cherry leaf scorch 

 (Gnomonia erythrostoma (Pers.) Auersw.) attracted the atten- 

 tion of Mr. W. Carruthers, F.R.S., Consulting Botanist to the 

 Royal Agricultural Society of England and of Prof. J. Percival. 



Mr. Carruthers published* an illustrated description of the 

 fungus, and stated that the disease was causing considerable 

 injury in cherry orchards in certain districts of Kent. The 

 remedy recommended was the systematic collection and 

 burning of the diseased leaves (which, as pointed out below, 

 remain attached to the boughs instead of falling in the autumn) 

 in all the orchards in the affected areas. Mr. Carruthers wrote : 

 " The removal and burning of the dead leaves has been 

 successful on the Continent, and there is no reason why it 

 should not be equally successful in Kent. No doubt this must
