as that for the common geranium plants 

 mentioned. These plants can often be 

 kept out of doors until well into Octo- 

 ber, if given the protection of a sash and 

 frame, or brought indoors on cold nights. 



OALLA OE ARUM ULLIES 



These lilies should be repotted, if they 

 require it, early in August. They like 

 a little humus or leaf mould in the soil. 

 One part sand, one part leaf mould or 

 black soil from the bush to six or seven 

 parts of good, rich, loamy potting soil 

 will suit callas very well. Use drain- 

 age in repotting them. If the growth on 

 these plants is well started at this time 

 of the year, it is better to top dress the 

 plants, as it is termed, This is done 

 by removing about an inch of the top 

 soil without removing the plant from the 

 pot, and putting in the place of the soil 

 removed, some good rich potting soil 

 composed of about one-half well rotted 

 barnyard manure and half potting soil. 

 This treatment, with an application of 

 liquid manure once or twice during the 



winter, will often give better flowering 

 results than repotting them. 



Toward the end of August is a good 

 time for repotting this class of plants 

 if they were not potted in the spring. 

 Use soil similar to that recommended 

 for call&s and pack it well around the 

 roots. These plants should be standing 

 out of doors during the summer months 

 where they are shaded from the hot sun. 

 They should be watered and sprayed 

 daily in hot weather. They are best 

 stood on a layer of coal ashes to keep 

 out earth worms. These last-named are 

 sure to collect where the soil is kept 

 moist, and often cause considerable 

 trouble by choking the drainage in win- 

 ter. A sprinkle of lime under the pots 

 will serve in place of the ashes if more 

 convenient. 



OINEKARIA AND CALCEOLARIA 



Seedling plants of these from seed 

 sown in July should be ready for trans- 

 planting. Transplant them when four 

 or five small leaves have developed, into 



shallow, well-drained flats, into a good- 

 loamy compost to which a good sprinkl- 

 ing of sand and leaf mould has been 

 added. A cold frame with a cotton shad- 

 ing over, raised at both ends to admit 

 plenty of air, is a good place for them. 

 The shade of a tree, if not too dense, is 

 also suitable. A piece of slightly shaded 

 glass placed over them and tilted to 

 throw off the rain during storms is ad- 

 visable. Green fly and thrip often bother 

 these plants. A good plan to prevent 

 their appearance is to place some tobacco 

 stems or tobacco dust, sweepings from a 

 cigar factory will do, around and under 

 the flats they are in. This will save a 

 lot of trouble oftentimes until later on, 

 when the plants can be more easily 

 fumigated than when in the frames out 

 of doors. 



Seed of pansies should be sown early 

 in flats for planting out in cold frames 

 in September to winter oVer. These will 

 make plants for early flowering in , 

 spring. 



The Importance of Right Greenhouse Construction 



A RIGHTLY constructed greenhouse 

 costs more to build, but less to 

 keep built. 



It means better plants — more blooms — 

 less care and lower running costs. 



It means a perpetual satisfaction in- 

 stead of recurrent disappointments. 



There are several distinct types of 

 acknowledged standard constructions, 

 each with its fast adherents. The under- 

 lying principle of all, however, is prac- 

 tically the same — that of making as light 

 a house as possible, and yet be as strong 

 as possible. 



When it gets right down to the last 

 analysis, results in any case are what 

 count. It is, however, an undeniable fact 

 that every once in a while, there is a 

 wizard sort of a plant lover who is able 

 to grow surprisingly fine plants under 

 most adverse conditions. Just as there 

 are some women who can break off a 

 slip from a plant and apparently careless- 

 ly put it in the ground, and it thrives. 



.Such persons, to the casual observer, 

 almost defy the laws of cause and effect, 

 but in reality their extreme fondness for 

 growing things supplies them with a 

 kind of second sense to which the plant 

 responds almost humanly. Give these 

 plant lovinpr folks a heavily constructed 

 greenhouse, with poor ventilation and 

 imperfect heat, and in spite of the handi- 

 cap they get surprising results. 



Taking your observation from what 

 they accomplish, you argue: if they can 

 do it, so can I. What is the use of 

 spending additional money for a house 

 built by the greenhouse expert*; when 

 one nf our carpenters here in town can 

 hiiilfl me one that will do? The answer 



L. W. C. Tuthill 



to that is : Are you sure you are one of 

 the wizard folks? Even if you are, 

 wouldn't you prefer to get the same re- 

 sults with less care and less actual run- 

 ning costs? Or wouldn't you rather have 

 a neat attractive glass enclosed garden 

 that looked its part, than a carpenter- 

 built affair, having the appearance of a 

 big box full of windows? 



Looking at it still another way — what 

 does your carpenter know about plant 

 requirements? Does he know whether 

 orchids should be grown in a north light, 

 or the best way to locate a house in re- 

 lation to the points of the compass to 



grow the best roses? What concern 

 does he give, that a wooden erected 

 house to be strong' enough, must be so 

 heavy as to seriously retard plant growth 

 because of the shade it casts? What 

 does he know about the correct slant of 

 the roof to obtain greatest deflection of 

 the sun's rays into the house during tlie 

 shortest days in winter when your plants 

 so seriously need every ray of light and 

 sunshine procurable? 



Does your local heating man know 

 about the temperatures necessary for dif- 

 ferent plants or whether hot water or 

 steam is best adapted to your particular
