In this part of the world window plants are not given their summer airing until May, but every opportunity is taken to let them have all the open air possible, by opening windows and sashes wherever practicable. People often complain that plants from greenhouses are too tender to stand the open sun, but it is only because they have been too much confined. If any plants growing in pots are yellow, or in anyway sickly, it is as well to prune them severely and plant for a year in the open ground. If they have insects on them these should be cleaned off before planting out, or they will increase under our dry summer sun. The red spider is best treated to a syringing of warm soap suds, and then to be dusted with sulphur; and the scale insects should have a painting with whale oil soap, and some say linseed oil. Many plants will have to be kept in pots all summer, and these are best set in partial shade. There are few more desirable room plants than the Ivy and Periwinkle in their numerous varieties. These should be potted now, and grown all summer. There are many things nearly, or quite hardy, that are not often kept in pots, but which would make good things for room culture, and these should be potted now.

Of these we may name Cotoneasters, Ma-houias, Berberis, Euonymus. These are very easily managed, and it seems to us that for those who have had little experience in plant growing, or whose conveniences are limited, it is just as feasable to have beautiful things easy to grow, as beautiful things that are difficult. Tea Roses, as well as China and Bourbon are good room plants. The old Hermosa and Pink Daily especially so. If young plants are turned out in the ground now, they can be lifted in September carefully, and if well potted, will flower freely all winter. This is the way professional florists grow Bouvardias, Carnations, and other popular flowers for cuttings. Very small plants are set in the ground at this season, and are quite large enough for potting by the fall.
