 be two inches thick by twelve inches. The front 

 plank should be two inches narrower. Place 

 the back plank two and a half inches above the 

 ground, and hold in place by driving stakes at 

 the end and middle. Continue the planking in 

 this manner until the desired length is reached. 

 The stakes should, of course, be nailed to the 

 planks. Place the front plank six feet from the 

 first, and sink into the ground so that the upper 

 edge will be five inches lower than the top of the 

 first, which makes a slant of five inches to carry 

 off the water. Continue this the same length as 

 the first, and you will then have a bed six feet wide 

 and of the desired length. Shovel out the loam 

 sufficient to bank the planks on the outside about 

 half the height, putting in spreaders to keep from 

 crowding in. Let the ground freeze about three
