duction had been selected for this experiment,therefore additional vege 
table organic matter in the soil was not absolutely necessary,but us¬ 
ing German peat moss as a mulch even on such favorable soil served as 
an insulator to prevent sudden changes of temperature,prevented evapo¬ 
ration of soil moisture,prevented the growth of weeds and kept the 
soil in a loose and workable condition with the above remarkable 
results.- 
One bale of German peat moss will cover 300 square feet of ground one 
inch in depth.
