Manuring of Fruit Trees.

the value of the method depends on the care and thoroughness 

 of the milking. 



Investigations have also been made by Dr. Wenck, of the 

 Agricultural Institute of Leipzig University, who states that 

 the milk which is obtained by this method after the ordinary 

 milking is not to be regarded as an addition, but rather as an 

 advance, on the yield of the following milking. The success 

 of the Hegelund method depends on the stimulating effect 

 exercised on the udder by the thorough milking, and he points 

 out that cows should be thoroughly milked, not because more 

 fat is to be obtained, but because the productivity of the udder 

 is by that means fully developed. 



The general adoption of the Hegelund method is not recom- 

 mended by Dr. Wenck, because any increase which might be 

 obtained is not, in his opinion, sufficient to cover the extra 

 cost. Only with a very skilled staff and with the closest 

 supervision could the method be made successful. Cleanliness 

 becomes more difficult of attainment than in ordinary milking, 

 and he thinks that the highest returns are to be obtained not 

 through the adoption of the Hegelund method but by the 

 employment of reliable and skilful milkers, who recognise the 

 importance of careful milking and are looked after by a capable 

 overseer. 



On strong clay it is known that the roots of fruit trees often 

 suffer through lack of air, and attention was drawn in an earlier 

 number of this Journal (Oct., 1904, p. 432) 



of Fruit ^rees * to a methoc * adopted in some parts of 

 Germany of securing the aeration of the 

 soil by placing layers of hedge brushings and similar material 

 beneath the roots when planting. Herr PfeifTer, of the Oppenheim 

 School of Fruit Culture, has recently given an account in the 

 Deutsche Landzvirtschaftliche Presse of the successful results 

 obtained by him by a system of green manuring, results which 

 he considers are largely due to the opening of the soil both by 

 the plant roots and by the ploughing in of the green crops.
