1908 List. 



The accompanying list of manures obtainable in New South Wales, together 

 with their composition, as guaranteed by the vendors, and their values, is the 

 result of the revision of the list issued in April, 1907. 



The list is published in the interest of the farmers, and it is hoped that it 

 may serve as a guide to those requiring any particular class of manure. 



It must be clearly understood that the figures given are not those obtained 

 by analysis of the sample by the Department. They represent the guarantees- 

 given by the vendors in accordance with the provisions of the Act. 



Where possible, samples have been taken from bulk by one of the officers 

 of the Department, and only those manures are inserted in the list which have 

 been found on analysis to be up to the guarantee. 



A word is necessary in explanation of the column giving the " values " of 

 the manures. These figures are calculated from the composition of the 

 manures as repres' nted by analysis, a definite unit- value being assigned to 

 each of the fertilising ingredients. The units on which the values here 

 given are computed are as follow : —
