==Lettuce== to be sown for succession, the quick-growing, tender-hearted kinds being the best to sow now.  Plant out from frames and seed-pans.  A few forward plants may be tied, but as a rule tying is less desirable than most people suppose.  Certainly, after tying, the hearts soon rot if not quickly eaten; and Lettuces as fine as can be desired may now be grown without tying, the close-hearting sorts being very much improved in that respect.

==Melon==.—­Sow again for a second crop in houses, and grow the plants in pots until they reach a foot high.  The early crop will then be ripe, and the house can be cleared and syringed for a fresh start.  From this sowing fruit should be ready about the beginning of July.  The frame culture advised for Cucumbers will be right for Melons, until the fruits attain the size of a small orange.  Then a thorough soaking must be given, and under proper management no more water should be necessary.  A dry atmosphere and free ventilation are essential to bring the fruit to perfection.  Stopping must be commenced early by pinching out the leader, and only one eye should be allowed beyond the fruit which are to remain.  Six will be enough for one plant to carry, and they should be nearly of a size, for if one obtains a strong lead, it will be impossible to ripen the others.  The remainder should be gradually removed while young.  The worst foe of the Melon is red spider, and it is difficult to apply a remedy without doing mischief.  Water will destroy it, but this may have disastrous results on the fruit.  The most certain preventive is stout well-grown plants.  Weakly specimens appear to invite attack, and are incapable of struggling against it.  Where plants are occasionally lost through decay at the collar, small pieces of charcoal laid in a circle round the stem have proved a simple and effectual antidote.

==Onion==.—­The plants raised under glass in January or February should be ready for planting out on some favourable day about mid-April.  If any mishap has befallen the sowings made in the open in March there must be no delay in resowing early in the present month, for Onions should have good hold of the ground before hot weather comes.  Onions for pickling should be grown thickly on poor ground made firm.  The plants are not to be thinned, but may be allowed to stand as thick as pebbles on the seashore.  The starving system produces abundance of small handsome bulbs that ripen early, which are the very things wanted for pickling.  The Queen and Paris Silver-skin are adapted for the purpose.

==Parsley== to be sown in quantity for summer and autumn supply; thin as soon as up, to give each plant plenty of room.

==Peas== to be sown again for succession.

==Potato==.—­Take the earliest opportunity of completing the planting of main crops.
