Whien you build a canal higher than the ground level, the width of the channel has little or no bearing on cost. The one indefinite factor in canal design is the matter of roughness. If you design a canal right for a clean condition, and it be- comes choked with weeds and brush, you have failed. On the oth- er hand, if you design the canal so it will deliver the right amount of water after it becomes choked up, and then it turns out that not a darned thing will grow in that can

You will have a job of erosion control which should be right up the alley of the Soil Consei-vation Service. Blind Spots of Growers Cranberry rr.'en show another blind spot when they persist in placing their flumes at the lowest point. This is often the poorest place. Take a reservoir flume for example. Low-point construction is the most difficult. If you moved the flume over next to higher ground you could build on hard bottom. And with the flume next to the higher sides of a bog, your frost water flowing along the high shores would protect the high parts of your bog where they now get little or no protection. Of course the bog itself needs some degree of drainage at its lowest point, but in a bog-below-bog layout, a SHARON BOX COMPANY, Inc.

Still another blind spot is the persistence of the main ditch down through the middle of the bog. This is the one place where you cannot get at it to clean it in August, when it needs it most. The main ditch along the shore is always ac- cessible, gives protection against pests from shore, whether veg- etable, insect, animal or human. The cross ditches can be made
