Only about one-tenth of this amount is used in the production of vegetables 

 near the large centres of population, and it is true that on the farm much more 

 of the manure produced could be profitably used in producing vegetables 

 for the farm home. Even so, it is reckoned that there would be a good 

 surplus of manure for the maize crop on most farms, with only ordinary 

 provision for collecting and saving it. 



On a large scale there is no other field crop but maize (apart from vege- 

 tables) which can readily and profitably make use of this manure. Apart 

 from the organic matter which is supplied in animal manure, it contains 

 appreciable amounts of nitrogen and potash, which are at all times (and 

 especially so at present) tl)3 most costly elements purchased in fertilisers. 

 A knowledge of this fact will enable tlie farmer to effect considerable saving 

 in his fertiliser bill when purchasing any of the commercial plant foods. 



The average amounts of the three chief fertilising elements in the solid 

 fresh manures of different animals are as follows : —

Owing to the conditions obtaining on most farms in the State where maize 

 is grown, it is difficult to obtain readily large amounts of the manure of any 

 stock, owing to their not being winter-housed, but the foregoing figures will 

 give an idea of the value of animal manure if it is in any way procurable. 

 For instance, a weekly gathering (^f manure from stables, cow-bails, small 

 yards, pig-hou.ses, and small runs on the average farm should result in the 

 collection of | to I ton of animal nianure (chiefiy from horses, cows and pigs), 

 which could V)e directly spread on the land or stored until winter. There is
