THE FLORAL WORLD AND GARDEN GUIDE. 



or the heat is kept up with linings. Any of the 

 nurserymen who advertise in this work can 

 supply roots. 

 Thermometer Scales.— 11. J. X.— To reduce 

 the foreign registers to Fahrenheit's, is a mat- 

 ter of arithmetic. The Centigrade ha3 0° for 

 freezing point, and 100° boiling, and is a truly 

 decimal scale. Reaumur's has 0' for freezing, 

 and 80° for boiling. Fahrenheit's is 32' freez- 

 ing, and 212' boiling— a very awkward and un- 

 scientific affair, yet the one adopted universally 

 in England. To reduce Centigrade to Fahren- 

 heit, multiply Centigrade by 9, and divide by 

 5, then add 32. To reduce Reaumur's, mul- 

 tiply Reaumur by 9, and divide by 4, then 

 add 32, Registering thermometers are not 

 only of the utmost value in the garden andthe 

 greenhouse, but the most interesting ^of all 

 philosophical instruments, not even excepting 

 the barometer. You can get excellent instru- 

 ments for minimum and maximum of Mr. Cox, 

 5, Barbican, or of Negretti and Zambra, Corn- 

 hill, London. 

 Waltonian Case. — W. H. D., and others. — It 

 is no fault of ours that the Waltonian Case has 

 had no place in our pages this season. The 

 experiments made by Mr. Hibberd, with a 

 view to substitute a candle for the lamp, were 

 quite successful, and we have seen the candle 

 which Messrs. Price and Co. are manufacturing 

 for it, and which is called (we know not why) 

 " Sherwood's for Waltonian Case." Mr. West, 

 the maker, is now constructing the case to 

 suit these candles, and one of the new con- 

 struction ought to have been in our possession 

 two months ago. As we have not yet received 

 it, we can only thus casually refer to it, though 

 by this time hundreds might have beeu sold if 

 Mr. West had taken time by the forelock. The 

 Waltonian Case is figured and described at 

 length as follows — "Rustic Adornments," p. 

 1(37 ; " Garden Favourites," p. 10-1; " Floral 

 Would," February, 1859. 

 Gloxinias. — Mrs. Gillispie will find, at page 10 

 of the January number, some notes on glox- 

 inias. The best time to start all this class of 

 plants' is the end of January — the heat should 

 be gradual at first. They quite enjoy the 

 moist heat of a cucumber bed or that of a tan 

 pit. The place to be heated is, we presume, by 

 the tone of the query, merely to be kept safe 

 by a temporary contrivance. The best of all is 

 a Waltonian case, because, while it keeps out 

 frost, gloxinias, achimenes, etc., may be started 

 in it, and every other kind of spring propaga- 

 tion set in action. One of those portable 

 stoves which burn patent fuel, with a pipe to 

 carry off the fumes into the open air, would be 

 cheaper, and quite sufficient. 

 Greenhouse Vermin. — A. T. B. — Your plants 

 are beset with thrips, and indicate a bad state 

 of health. Give more air, and syringe the 

 plants with tepid water, in which a little size 

 and soft soap have been dissolved, and in a few 

 hours afterwards, syringe again with pure tepid 

 ■water, or use a solution of Gishurst compound, 

 two ounces to the gallon. Small plants so 

 affected should be put under a sea-kale pot, 

 with a little spirits of turpeutine in a saucer, 

 and then submitted to a gentle heat. The best 

 method of keeping all such enemies at a dis- 

 tance, is to be rigid as to cleanliness. 

 Planting. — Bob. — Trim off jagged and bruised 

 roots by cutting the parts clean away with a 

 sharp knife. Tread the hole firm ; throw in 

 some fine and rather dry stuff. Then thrust 

 into the space under the collar some lumps of 

 stiff soil, so thatthere will be no hollows among 

 the great divisions of the root ; fill up so as to 

 cover all the fibres close with the finest and 

 driest of the soil, and tread very firm. Instead 

 of one stake, it is better to use three lengths 



of tarred rope, fastened to pegs in the ground, 

 in the way that stays are put to a flagstaff. 



Siephanoiis Floribbnda. — T. Gurney. — This 

 should be managed in the same way as Mande- 

 villea suaveolens. It will winter in a tempera- 

 ture of 45" to 55° and must be kept rather dry. 

 During its growing season, it requires a tem- 

 perature of 60 3 , increased steadily to 85° as the 

 season advances, and the more heat the more 

 water. In a cold greenhouse it may not perish, 

 but it never comes to any good. The proper 

 soil is equal parts loam, peat, leaf-mould, and 

 silver-sand. It is a grand plant for a warm 

 conservatory when it reaches the roof. 



Fames of Ferns — J. M. B. — 1. Scolopendrium 



(?) 2. S. endivifolium, very beautiful. 



3. S. multifidunr, the best of the varieties of 

 this section. 4. S.undulatum. 5. S. (?) 



6. S. angustifolium, an interesting variety. 



7. Polypodium cambricum, a fern of exquisite 

 beauty, aud striking for its vivid green colour. 



8. P. serratifolia. 9. Doodia (?) 10. 



Polystiehium (?) 11. Asplenium ruta 



muraria, an interesting British fern. 12. Sco- 

 lopendrium bifidum. 



Heating a Greenhouse. — Y. M. 8. — A house 

 measuring 12 feet by 6 feet is not sufficiently 

 large to need hot water ; a flue will serve the 

 purpose well, aud be cheaper and simpler. 

 The sides should be brick in preference to 

 wood, and the cost but little different. Four- 

 inch work will do. 



Flower Border. — G. Johnson .—Back row, Ze- 

 linda dahlia; in front of that, White Unique 

 geranium ; then Tom Thumb ; and in front, 

 Lobelia speciosa. Back row, Captain Ingram 

 dahlia ; next, Ageratum ; then Attraction 

 geranium; and in front, Cerastium tomen- 

 tosum. 



Vallota puri>lrea. — A. B. C. — Plant in au- 

 tumn, and manage as directed at page 11 of 

 last month's number. 



Various. — M. J. J. — The seeds were distributed 

 long ago, and none of them are left now. — N. S. 

 — We don't know the plant you name. — J. 2i. 

 — Hovea purpurea may be cut in after flower- 

 ing. Hard wooded plants come on fast in peat, 

 and if the purchaser gets them before they are 

 lanky, he may do well with them. They are 

 grown to sell. The article on "Weeds" had 

 Mr. Chitty's name attached by mistake, Mr. 

 Chitty wrote the charming paper on ferns. 

 Some parts of Kpping Forest are very rich in 

 ferns. — J.F., Coventry. — There is no thoroughly 

 good book on bulbous flowers, and a great 

 many points must be cleared up, both in botany 

 and horticulture, before such a book can be 

 written. Belladonna. — Lilies must be planted 

 in Jul}'.— S. S. S. — For the first, send to Messrs. 

 Dray and Co., London Bridge ; the cost will be 

 from Is. to 10s. For glass of all kinds send to 

 Messrs. Phillips, ISO, Bishopsgate Street With- 

 out. A hand syringe should have a small tube 

 near the handle, and they are always made so. 

 The 'size of a greenhouse depends on the 

 spot it is to occupy. Look over the papers on 

 the subject in last year's volume, and judge by 

 the estimates and plans. — From?. — The papers 

 have only been suspended to moke room for 

 others of seasonable value. To find the editor 

 of The Field, the " Strand, London, W. C," 

 will be sufficient. Shall always be glad to hear 

 from you— <S'., Way month.— Can't do it. We 

 started on the plan of sticking close to hor- 

 ticulture, and we have stuck close. We shall 

 see you some da}', and orally thank you for 

 your hearty good wishes. — H. N. O.— Yes, as 

 soon as possible. Such instructions areneeded. 

 — N. Maltby. — Any good seed-list will give you 

 the information you want. It would be a 

 waste of space for us to print the list you pro- 

 pose.
