SOIL AND CONTOUR OF THE SURFACE OF THE GROUND.

To provide good drainage and adequate ventilation for the bee cellar

without making any special ventilators, it is desirable to build it in

a sandy hillside. If it is possible to choose a place for the cellar

where the snow drifts deeply, this will afford a valuable addition

to the insulation of the cellar. If the cellar is on level ground,

drifting of snow may be increased by the proper building of open

fences, such as are used to prevent drifting over railway tracks.

to build walls and a floor for the cellar and to make adequate

provision for the drainage of the cellar. The hillside cellar has, the

great advantage of having easy drainage.
