With the usual shortage of labor in the harvest season and the frequent
occurrence of showers, to secure sweet, unmolded hay it has become
necessary to cover the hay cocks with a canvas or muslin cover. The
best weights to hold down the covers are made of concrete. Mix the
concrete 1 part Portland cement to 2 parts sand, mold them like
doughnuts or as cakes with a galvanized wire loop, and set them aside
in a damp place for 7 days before using.
