I would give less space to them than to any other of the cane fruits. I would give rather more to the black-caps, and still more to the very best varieties of blackberries. There are few markets in which good cultivated sorts of the latter fruit are often found in sufficient abundance to supply the demand. The wild berries are usually plentiful, and good enough when eaten out of hand in the woods or the berry patch, after a battle with the briars. But notwithstanding all the ro-romance of the "fruit's wild flavor," they do not compare, for table use, with big, ripe, luscious Lawtons. The cost of gathering red raspberries is a serious drawback to the profits. The larger blackberries fill the baskets so rapidly that the cost is hardly appreciable.
While the fruit garden must claim much attention this month, we cannot wholly neglect the vegetables or we should suffer for it by and by. That part of the garden already planted must have attention. Perhaps the weeds have not started much yet, but if the plants are up the ground must be worked. April showers sometimes come down with force enough to pack the soil pretty hard. The hoe and rake will be constantly needed to keep the surface loosened. Other plantings besides those we instanced last month must now follow in quick succession. Every week from now until midsummer should see something go into the ground, so that as the season progresses we may have, each week, something new for the home table and for market. We shall soon be gathering onions, beets and radishes for market. The ground upon which they are grown should be rich and in good mechanical condition - kept loose and mellow up to the very day these crops are taken off. If it is in such good heart, the very best way in which it can be employed for a second crop is to set plants of early summer cabbage in the rows as fast as any open places are made. The larger roots will be pulled first, and thus vacant places will be made in which plants can be set, sometime before we could wholly clear the land.
If plants are set in every alternate row of these beds they could be about the right distance (two feet) apart. The spaces may occur with some irregularity; set the plants as nearly as possible two feet apart in the row, and if the rows are straight one way there will be no difficulty in cultivating them. To have the plants handy, a bed should be sown (in the open ground) as near as can be to the place where we shall use them. Then we can pull one or a hundred plants and set them in as wanted, leaving the ground unoccupied hardly for an hour. If this bed is sown by the tenth of this month the plants will be ready in time, and will mature just in time to follow the first early cabbage grown from hotbed plants. The advantage of having this bed of plants "handy" cannot be too strongly impressed. If it is a long distance away, it will hardly seem worth the trouble to go to it and pull a few plants at a time. But when close by the work will seem so attractive that we shall let very little ground remain unoccupied.
