great loss from shattering. It has also been observed by 

 certain experimenters that the quality of constant fer- 

 tility, or of producing " well filled " spikes, is greatly

 probably little realize the loss in yield that is simply the 

 result of inability of the variety to fill its spikes. There 

 are both winter and spring varieties of spelt, and some 

 of the former are very hardy. Certain varieties are also 

 rather drought-resistant, but with some exceptions they 

 are more or less subject to damage from rust.
