well. One Peach to every square foot of trellia is deemed Buffi- 

 cient, and the wood must be fully exposed to light and air. Give 

 the border a thorough watering when the fruit begins to swell, 

 and it will not require more until the crop has been gathered, 

 when the trees may be again well syringed, and if necessary the 

 borders watered. 



If there is any trace of green fly in later houses it must be 

 deftroyed by famigaling on two or three nights in succeBsion. 

 This pest causes the leaves to curl, and will, if it is not de- 

 stroyed, prevent the growth of all the shoots on which it is to 

 be found. The safest remedy for mildew is flowers of sulphur. 

 The best way to apply it is to mix a good handful with a small 

 quantity of strong soapy water, and stir the mixture in three 

 gallons of water, with which to syringe the trees. If they have 

 become badly affected a second application may be necessary. 



PLANT STOVE AND OBCHID HOUSES. 



These Btmcturea require considerable watchfulness now. 

 "When the sun shines unobscured by clouds it acts with great 

 effect upon the glass, but accompanied with the sunshine may 

 be biting east winds, which would do much injury to tender 

 plants if allowed to blow directly upon them. It is, therefore, 

 often the best way to shade and admit but little air. Although 

 many plants would suffer from sunshme and abundant venti- 

 lation others are benefited by it, and it is necessary to make a 

 compromise. The shades ought always to be fixed to rollers, 

 which can be run up or down by pulleys in a moment, and the 

 blinds will not then be left down when they ought to be up. 

 The rule must ho to shade only when the Bun shines, and to 

 close the houses early in the afternoon, when the temperature 

 may run up to 85° or 90° with sun heat. The nights have been 

 very cold, but it has been a great advantage to close with sun 

 heat; and with a still atmosphere and 10° of frost no more arti- 

 ficial heat is required than is necessary with no frost but a cold 

 wind blowing. 



Hardwooded summer-flowering plants are now showing their 

 flower buds, and many of them can endure almost any amount 

 of heat. Ixoras do better with 75° at night until the flowers 

 are expanded ; with plenty of moisture in the atmosphere and a 

 little bottom heat they make splendid growth. Bottom heat is 

 not essential to them, nor should it be more than 85° or 90°. 

 Many other occupants of the stove would not thrive, or at least 

 they would not enjoy continuous health, under such circum- 

 stances. If the plant stove is large it is most desirable that it 

 should be divided into two compartments, one with a tempera- 

 tare of from 55 to (JO , and the other 10" higher. 



Orchids are starting into free growth now, and many of the 

 summer-flowering species are showing flower. In the cool 

 house OdontoglosBum crispum is always in flower ; as soon as 

 the growth is completed the flower spikes throw up. Masde- 

 vallia Harryana is not only the freest to flower of the species 

 but is singularly regular as to the time of flowering. Oar plants 

 show for flower about the end of March, but the flowers do not 

 open until early in June. It is not possible to name any season 

 when it would he best to shift Odontoglossums ; we generally 

 Bhift them just before they start into growth. MasdevalUas are 

 repotted after they have finished flowering. Epidendrum vitel- 

 linum and the variety majus are very distinct and useful Orchids 

 for the cool house ; we had flower spikes of both last year that 

 lasted in tolerably good condition for three months. The bril- 

 liant orange-red flowers are exceedingly effective amongst the 

 more sober tints of Odontoglossums. 



It is necessary to shade the cool house from sun at this season, 

 as the young growths are easily injured. — J. Dodglas.

TO CORRESPONDENTS. 

 •,• All correspondence Bhould be directed either to " The 

 Editors," or to *'The Pablieher." Letters addressed to 

 Mr. Johnson or Dr, Hogg often remain unopened unavoid- 

 ably. We request that no one will write privately to any 

 of onr correspondents, as doing so subjects them to un- 

 justifiable trouble and expense. 

 Correspondents should not mix up on the same sheet questions 

 relating to Gardening and those on Poultry and Bee eub- 

 jecte, and should never send more than two or three 

 questions at once. All articles intended for insertion 

 should be written on one side of the paper only. We 

 cannot reply to questions through the post. 

 BooK3 (S. £.).— Our "Flower Garden Manual" and "Kitchen GsjJen 

 Manual." Yoa can have them post free if you enclose ten postage etampa 

 with your address. 



Wild Violets {E. D. B.).— The yellow flowers are those of Viola lutca, 

 cotomon in Somersetshire. The purple flower is the common Viola odorata, 

 rather darker in colour than usual, which is not uncommon when the plants 

 are highly cultivated. 



Climber not Floweeinq [W. W.). — "We believe it iaLapageria rosea, but 

 no oae could be certain from only eeeing two dead leaves and 3 inches of an 

 unripe shoot. Growing as you state it does in the shaded part of the green- 

 house, and overmoist from the cnnstant dripping of the water-tap, suffi- 

 ciently account for its being flowerleas. More light and less water would 

 cause it to flower. 



Marlchal Niel Rose Stem Spotted (Mrg. G.).— The black spot upon 

 the stem of the shoot sent is, we think, a result of the syriDging, which from 

 the moisture restiug in drops upon the stem causes a disorganisation of the 

 tJFsues. resulting in the parts so subjected b^ing blacked. The only remedy 

 is to admit air more freely and not feed so highly ; the plant, we fehould think 

 from the foliage, being very luioriaut. 



Camellia not Flowering (P H. B.).— Camellifls require light, but with 

 Bhade for the foliage from s-orching sun in summer. Your plant you say is 

 *' planted out in loam and peat under a large tree Fern," and we apprehend 

 that both plants are in the same border. The shade of the Fern, and that 

 also under a shaded roof, is too dense for the Camellia, and the border will 

 for a tree Fern be in such a state as to be mud for Camellias. Either you 

 must find a more suitable position for the Camellia or put up with its 

 fewness of flower buds and their dropping. 



Furnace for Greenhouse (C. Jones). — The furnace should be 2 feet 

 long. 1 foot wide, and 1 foot hit{h, or four conrBCS of bricks, and arched over, 

 which will give about one-third greater height in the centre. The furnace 

 door will with its frame require to ba I foot square, the door beiug, of course, 

 less by the size of the fra^e. The ashpit should be 1 foot wide and deep, 

 and should have a door to regulate the draught. Tbe furnace mu«t be square, 

 not rounded ; but the flue may be rouoded at the angles, keeping the same 

 width as if the flue were square. The flue from the furnace should have a 

 clear rise of at least two-thirds the depth of the furnace, the bottom of the 

 flue to be 9 inches above tbe furnace bars. 



Ehythroxylon coc\ IW. J. P.).— Erythroiylons are tropical trees or 

 shrubs of no particular beauty. They are chiefly found in South America, 

 also in the Mauritius and Madagascar. Dr. Hogg in his " Vegetable King- 

 dom" states that the wood of nome of the species is of a reddish tinge, 

 hence the name of the tree from erythroi, red, and xyloit, wood ; and that 

 •' the leaves of E. coca are masticated with the seed of Chenopodium quinoa, 

 and are said to stimulate the nervous system in the same way as opium, all 

 the effects of which the coca possesses in a high degree." The plant is re- 

 puted to be extensively used by the miners of Peru for its stimulating 

 properties.
