CH. x] Liquid Manure 177 



is wanted. Defective roofing and spouting should be 

 made good so far as possible to avoid washing by rain. 

 If made in open yards the manure should as soon as 

 convenient be hauled out and tightly clamped. 



The clamp should be so placed that it is not unduly 

 exposed to rain. Shelter should be provided in the form 

 of a layer of earth, thatched hurdles, corrugated iron 

 sheets, etc. If any black liquid is running away it is a sign 

 tliat shelter is insufficient and that wastage is going on. It 

 is not sufficient to collect the liquid, though this should be 

 done ; steps should be taken to provide more shelter also. 

 The clamp should not be disturbed until it is wanted. 



If it is possible to avoid maldng the clamp by putting 

 the manure straight on to the land and ploughing it in, 

 so much the better; especially in the regions south of 

 the Humber. As far as possible summer storage of 

 manure should be avoided. 



II. Manure 7iiade from dairy cattle. This has usually 

 to be thrown out daily. It should be well protected from 

 rain. The worst plan is that seen in some of the northern 

 dales where the manure is thrown out of a hole in the 

 wall and left exposed to weather, with the result that 

 streams of black liquid flow away. A much better plan 

 is to cart the manure to a dungstead as is done in 

 Cheshire and other parts of the country. 



Liquid 7nanure. Special care should be taken of the 

 liquid manure draining from the cow sheds. This should 

 be run into a tank^ and applied when convenient to the 

 land. It may go on to grassland at almost any time, and 

 to arable land after the autumn and before the middle or 

 end of May. It is specialJj^ rich in nitrogen and potash as 

 shown in Table XL
