alumina, and of the same after treatment with sulphiu'ic acid ; analyses 

 of a number of samples of muck, and a comparison of the average com- 

 position of the same with barnyard manure (average of -1 analyses 

 made by the Massachusetts State Station); remarks on the methods of 

 using muck, directions for composting, etc. xVnalyses are also given of 

 bat guano and rice hulls, the latter with reference to its food ingre- 

 dients. 



The muck contains a great deal more nitrogen iind niucli less pota-sli and jdios- 

 phatc than the barnyard manure. 



The muck contains comparatively much nitrogen, Vjut is dcticient in ptjtash and 

 phosphate. Hence in the use of muck as a fertilizer one shouM oxjiect that it 

 would need to be supplemented by potash and phosphate. ' » * 



Fifteen samples of our muck when perfectly dry contained between fdi and !•? per 

 cent of organic matter, 12 of the 15 contained from 2 to 4 per cent of nitrogen, 3 

 less than 2 per cent, and 1 less than 1 per cent. Five samples c«>ntaiued less than 

 5.5 per cent of organic matter, 4 of which contained between 1 and 2 per cent of 

 nitrogen, and 1 less than 1 per cent. 



As is well known, plants of diiierent kinds and different parts of the same plant 

 contain different amounts of plant food. In the yK-rfectly »lry state, i)ea vines, for 

 example, contain about 2 per cent of nitrogen, and wheat straw only about 1 per 

 cent. One would naturally expect that a muck if formed l»y the disintegration of 

 the former would contain more nitrogen than if by that of the latter. • » * 



In judging of the value of a muek, three things at least are to be taken into 

 account: (1) The kind or kinds of plants from whieli formed; (2) the quantity of 

 organic matter in the muck; and (3) the stage of decomposition.
