Iv. QUEENSLAND AGRICULTURAL JOURNAL. [1 Noy., 1898, 
an accurately weighed quantity—say 11b. ‘This quantity may then be dried 
in the sun, taking care that nothing is lost, and when dry put in a bag and 
forwarded for analysis. The green samples may also be forwarded without 
drying in fruit-preserving jars. 
To collect information about value of green manures, it is best to plot out 
exactly one square yard in the field covered with the plant, not picking out a posi- 
tion where the growth is very heavy or poor, but about a fair average. Four pegs 
are driven into the ground at the four corners, and string stretched between 
them ; with a sharp spade all the plants are cut along the strings, so as to get 
really the growth of one square yard. The plants are all collected and 
accurately weighed, passed through a chaffcutter, and the sample for analysis 
taken as above described. In many cases the roots may be also pulled out, 
weighed separately, and a sample forwarded. 
The samples have to be accompanied by a description of the crop—when 
planted, how old when cut, if the land was manured or not, weight of crop per 
acre or per square yard, and weight of the sample forwarded when in its green 
state. In the case of green manures it is generally best to take the samples at 
the same time when ploughed under, just after flowering.
