FRUIT GROWING FOR HOME USE IN THE GREAT PLAINS. 15 
It is made by excavating the earth and mounding it up somewhat 
about the edge or rim of the reservoir. The inside is then puddled 
with clay or in some other way made sufficiently impervious to water 
to prevent seepage. The water may be siphoned out for distribution. 
SPRAYING. 
On account of the dry atmosphere in the Great Plains region, fun- 
gous diseases will probably not be serious, but the more common 
insect pests may be expected to do more or less damage unless means 
of control are applied. The insect problems, however, are doubtless 
so similar to those of other regions that the methods of control that 
are effective elsewhere will prove satisfactory here.
