Grass Preservation. 



Hay. — Excess grass in a mature stage during June and July can be made 

 into hay. The grass is cut and dried in the sun. When lulled and dry, 

 it is made into a stack, where it ferments — more or less. If rain has fallen 

 on the hay it will have lost some of its feeding value. In general the losses 

 during haymaking and maturing in the stack are about 40 per cent.
