WHEAT, AS A NEW SOUTH WALES PRODUCT.

or from land that has been manured to mix with the poorer lots. 

 There has not been an opportunity yet to test, amongst ourselves, 

 more closely than the process followed by the millers regarding 

 the precise effect of manuring upon the proportion and quality of 

 the gluten, but we have the following from the Lawes and Gilbei't 

 tests : — 



I. — Analyses of parcels of red wheat grown in the same year, 

 without manure, and with manure : — 



The foregoing will, I believe, be found to come closely to the 

 experience of Australian millers, who find that the weight per 

 bushel of wheat is not, as a rule, a suificient ci'iterion for what is 

 required for high-class flour — the gluten with its albuminoids. It 

 is thus seen that manuring has the desired effect in improving the 

 quality. That the quantity, in the case of the farmer, is improved 

 by the same process of fertilising, is well known, and need not be 

 discussed here. 



This brings us to the all-important question : What are the 

 ingredients necessary for a perfect wheat fertiliser ? In order to 

 meet that requirement effectually, it is first necessary to see how 

 a wheat crop is made up, or rather what it takes from the land. 

 And here, fortunately, we have Australian experience for com- 

 parison with the te.sts carried out at Rothamsted during twenty 

 years.
