two or three strong eyes being quite sufficient.  This can easily be accomplished as the sets are laid into their places in a shallow drill opened on the top of the ridge.  The sets may be put a foot apart, and have four inches of fine soil over them.  Prick the ground over with a fork between the rows, leaving it quite rough, but regular and workmanlike.  The Peas will soon be visible and require attention.  Draw a little fine earth to them, and stake them carefully with small brushwood.  If snails and slugs appear, give dustings of lime or soot, and as soon as possible supply stakes of sufficient height and strength to carry the crop.  By the time the Potatoes begin to show their shaws the Peas will constitute an effectual shelter for them against east winds, and it will be found that the morning frosts that are often so injurious to Potatoes in the month of May will scarcely touch a crop that has the advantage of this kind of protection.  But to that alone it is not wise to trust.  One serious freezing that blackens the shaws will delay and diminish the Potato crop.  Therefore, as the green tops appear, cover them lightly with fine earth from between the rows, and if necessary repeat this, always allowing the leaves to see daylight.  When a sharp frost occurs, it will be advisable to cover the tops with a few inches of light dry litter in just the same way that a bed of Radishes is protected.  There are many other methods of saving the rising shaws.  A plank on edge on the east side of a row will suffice to tide through an ordinary white frost.  Mats or reed hurdles laid on a few stout pegs will also answer admirably, but care must be taken that the plant is not pressed down, and the covering must be removed as soon as the danger is over.

Crops grown under walls will be ready first, and those in the beds will follow.  Spaces between the trees of a fruit wall may be planted with Potatoes, without injury to the trees.  Those grown on the south face of a good wall will be ready for table three weeks in advance of the earliest crops in the open quarters.  But east and west walls may be made to contribute, and even north walls are useful, if planted a week later and a little deeper.  In all cases the sets should be put close to the wall to enjoy the warmth, and dryness, and shelter it affords.  When the crop is lifted, the soil specially laid up for it may be taken away, or scattered over the border.  But the bulk will be so slight that it will not matter much what becomes of it.  However, in a new place with a clay soil it may be prudent to remove it, and keep it ready as an aid in seed sowing, for there are times and places where a little fine stuff is worth a great deal to give a crop of some kind a proper start.
