The weather at this season is usually too hot for enjoyment under a glass roof, and most of the plants being outside, there is little to be done in this department excepting watering temporary occupants; such plants as Coleus and Caladiums requiring a very liberal supply with an occasional watering with liquid manure when the pots are filled with roots, and a liberal application of the hose or syringe to every part morning and evening of bright days. If this is neglected, such plants as climbers on roofe will get smothered with insects and dust.

Late Camellias will be now best out-of-doors in a shady place. These plants, with others, removed out earlier in the season, will require strict attention to watering, a good application of the hose over the foliage at frequent intervals being of great service in keeping plants clean and free from dust, but we do not recommend an indiscriminate watering to the soil of large plants with the hose. In this case some get more than required and many do not get enough, the surface only being moistened while the ball of roots is often dust dry, which often is the cause of sudden death in such plants as Heaths and Azaleas, and dropping of the buds of Camellias.

Climbers on roof should now be in full beauty. No warm greenhouse should be without a good plant of Stepharwtis floribunda. This plant is in full beauty during June and July. We have a plant which is planted in a small bed and trained to wires near the glass roof of a warm house; it has hundreds of bunches of its beautiful white, sweet-scented flowers, than which nothing is more lovely either for wedding bouquets or funeral wreaths. We feel much surprised to see this beautiful plant is not more cultivated in this country. All our lady visitors are charmed with it when in full flower, and it is very easily grown, requiring abundance of water when growing, and very little during the winter. The flower being produced on the young wood it requires liberal pruning during the winter, and a bunch of flowers will show with eaoh pair of leaves.

Passiflora princesse is a capital companion to the Stephanotis, and it has the additional charm of flowering all the year round. Its beautiful racemes of scarlet flowers are very useful to cut for hanging around tall vases of cut flowers for rooms and churches; we use them during the winter for Plymouth Church.

Tacsonia Buchatiani is another fine climber, but it requires a large house; it being a very rampant grower would Boon overgrow everything else in a small house, but the flowers are of the most magnificent scarlet, more of the color of Poinsettia bracts than any flower I have ever seen. . This plant sends out a single flower from the bare of each leaf, so that it is continually in flower.

Thunbergia Harrisii should be pruned in and thoroughly cleaned to induce a free growth for flowering next winter.

Double White Primula if not planted out of pots in a frame, will require shaking out from old soil and repotting into smaller pots in good, free, sweet soil, and be placed in a shady frame to be kept rather close in the day, but with plenty of air during the night. These plants do not like free watering over the foliage; the leaves, and often the heart of the plant will rot off during our hot summer. The plants make but little progress, but as the nights become longer and cooler, they make rapid growth.

Poinsettius will require potting into the pots they are intended to flower in. Tops of young shoots put into small pots and rooted in a close frame, will make nice little plants for decoration of rooms or for front row in greenhouse. If these plants are not placed out-of-doors, give them a good, light position with plenty of ventilation, but we prefer these plants outside during the hot months, if convenient.
