(7) ‘The strength and stiffness of straw. 
(8) Flag development suitable to the climate. 
(9) The constitution and vital energy of the seed and plant. 
(10) The capacity of forming a maximum weight of solid matter 
with a minimum amount of moisture. 
(11)- The capacity of forming a relatively large amount of grain 
to other solid matter. 
Each of these factors need to be specially developed according to 
the soil and climatic conditions of the district the varieties of wheat 
are grown in if the resultant grain is to be a perfect sample. Thus 
the heavy-flagged wheats, with their wide surfaces and sappy texture, 
need a long, even ripening period, which-would be denied them in the 
northern wheat areas of this State. The evaporation from the leaves 
would be so great that the roots are unable to supply sufficient moisture 
to replace that evaporated, and though highly prolific in one country, 
would possibly give the lowest yields and shrivelled grain in another 
possessing a short spring followed by hot winds; whereas another variety 
with thin scanty flag would succeed well. The humidity of the atmo- 
sphere during the early summer, when the crop has ripened, is another 
point of consideration, since prolific varieties in climates with a fair 
amount of humidity in the atmosphere need not possess such holding 
power for the grain, enclosed within the glumes, as in the varieties 
suitable to hot and dry climates. Hence it is one of the reasons the 
great Fife wheats of Canada do not give such returns here; they shed 
their grain too readily before it is harvested. By cutting the erops 
and threshing them, this defect is more or less ameliorated. 5 
Tux Bust Prants, nor rue Best Ears, sroutp Be SELECTED. 
It is usually thought that in selecting plants for the stud plots, . 
the best ears are the desideratum. If it happens they are selected from 
the best plants it is so; but, in selecting, the primary object in view is 
to select the best plants, hence the reason, in the stud plots at the 
College, the seed is sown singly in the rows, each seed being about 
6 inches apart. Thus, every plant may be studied. A few of the plants 
may have one or more very fine ears, and a number of sickly small 
ones. It is not likely they will be as prolific as the plants which have a 
number of good even ears on stalks of an even height and very few 
small ears are in evidence. Plants on the outside of the plot, and others 
that may be accidentally placed under favorable conditions, should, as 
a rule, not be chosen. In every instance the best seed of the best plants 
should be used. This corresponds in a measure to heavy grading when 
dealing under crop conditions. ‘

In selecting the plants, choose those with uniform, compact, and well- 
filled ears possessing the greatest number of spikelets and fertile florets, 
firm to the touch when grasped in the hand, the glumes of a firm texture 
but not coarse, and possessed of a healthy glaze, which aids in throwing 
off excess of moisture in wet weather, and to some extent indicates 
greater rust resistance. The shape of the ear, in its connexion with
