Roses layered now, aud left uudisturbed 

 till April next, will then be found well 

 rootad, and may be takea up aud potted 

 for bloom the following autumn. 



Vines forced early will aow be disposed 

 to break. Lot them have a temperature of 

 55' to 63", not higher, till the leaves are 

 developed.

Varnished Tiffany, Pea-teellis, Waltonian 

 HsAiiifG. — You will much oblige ouo of the 

 earliest, subscribers to the FLoaii. Wokld, by 

 stating in the nest number whether tiffany, 

 which is of a s ) much moie open texture 

 th.ra calico, would answer for beiuij v>ir- 

 nished, aud also by givino; a recipe for a 

 cheap and transparent varnish. Copal is very 

 expensive, and as any liiud of cloth used would 

 absorb a large quantity, the cost of the varnisU 

 would greatly exceed tliat of all the other ma- 

 terials of the structure. I would suggest fast- 

 ening the cloth at the top by rings a d hooks 

 of brass, and with tie-strings at sides and bof- 

 tom, as well as round the rafters, etc. This 

 would allow of the removal of the cloth when 

 desired, without disturbing the siteleton of the 

 fabric; the sides could be looped up also at 

 times for ventilation, etc. Zinc wire lattice at- 

 tached to posts inside, forms an admiruble and 

 cheap support for peas. The wire should have 

 a wide mesh, and need not be closer than ten 

 inches above the ground, if put u,) immediately 

 after the last earthing of the row. Ttie posts, 

 six or eight feet apart, should incline outwards 

 a little at the top. The tendrils of the peas 

 will take sooner by having the wire close to 

 them, and room should be left for the branch- 

 ing of the peas as they advance in growth. 

 The wire, rolled round an end post, may turn 

 the corners. The whole apparatus will last a 

 lifetime, with ordinary care, and look neat and 

 tidy, as it is inexpensive and easily procured, 

 which rods are not. The Vidth can be adapted 

 to the height of sorts cultivated, and if painted 

 pea-green, will be an invisible green al-^o. I 

 may also say that I fhid German floats (which 

 cost Gd. per box, containing some hundreds) 

 answer admirably for heating a Waltonian 

 case; of course colza oil is the best, and if a 

 broad surfaced vessel — say five inches — be used, 

 two or even three may float on the surface, and 

 they will burn while the oil lasts with a steady 

 heat an I uo trouble, except renewing oil and 

 floats every twelfth hour or so. A great advan- 

 tage attending their use is the increase or dimi- 

 nution of heat to any amount, as you light 

 more or less of these inoffensive littlt? lamps, 

 which emit neither smoke or smell. The flame 

 should reach within half-an-iuch of the boiler, 

 a'J it will fall a little as the oil is burned. The 

 great secret of this invaluable case is the re- 

 moval of cuttings or seeds, etc., as quickly as 

 possible after rooting or germination. I find 

 plants suffer in it by too long residence. — Omi-

[We have no experiences of varnished tiffany, 

 and a priori are unfavourable to the proposal 

 of varnishiuif it. We slioula prefer for such a 

 purpose unbleached calico. Nevertheless, tif- 

 fany might answer, and we shall be gl ul to hear 

 if it does. Here is a recipe for rendering it 

 waterproof: Old pale linseed oil, three pints ; 

 acetate of lead, one ounce; white resin four 

 ounces. Grind the acetate wiih a little oil, 

 then add the rest of the resin. Incorporate in 

 an iron pot over the flre and apply hot with a 

 brush. Perhaps some of the cheip varnishes 

 would serve the same purposes, but we cannot 



say, having long given up all such preparations 

 owing to the clieapness of glass.] 



PORTULACCAS FROM SeLF-SOWN SEED. — I wish 



through your publication to make known to my 

 fellow-gardeners, that the portulacca need not 

 be considered a tender aanual. Last summer 

 I had a bed of this plant in a soutli aspect. In 

 the autumn aud this spring the eiirth was dug over 

 and stirred with an unsparing hand, but to my 

 astonishment tUerehas appeared a very healthy 

 plant of the scarlet portulacca, self-sown. If 

 the seed could withstand the intense cold of the 

 last winter by the sea-side, surely we need not 

 fear sowing it in the autumn in the open ground, 

 wtien finer and stronger plants would be gained 

 thiin bv raising in a hot-bed and transplanting. 

 —J. E. N. 



[We had self-sown plants of mimulus on a rockery, 

 green and Iresh all last winter, that have 

 flowered magnificently since June. For portu- 

 laccas a dry position is essential in all eases — 

 moisture is deatu to them.] 



Fumigating-. — We have received from Messrs. 

 Griffiths and Avis, of Hiijh .Street, Coventry, a 

 sample of tobacco paper, and with it an iron 

 pot adapted for the slow combustion of the 

 paper, aud the delivery of a cool and long con- 

 tinned volume of smoke. The pot is six inches 

 in diameter and seven inches high; it has a 

 handle, and one vent hole near the bottom to 

 keep up the combustion. It is the simplest of 

 all fumigators, andean be used also for deliver- 

 ing the fumes of sulphur and lime for the 

 destruction of red spider. 



Chrysanthehuii TiiAiNitfG. — " Just as the twig 

 is bent the tree's inclined." By placing deli- 

 cate little tults of cotton wool among the shoots of 

 chrysanthemums that are under training, the 

 leader can be sustained and the branches de- 

 pressed from the time they are half an inch 

 long. The wool to be increased till the shoots 

 are hard enough to be tied into shape. — Inno- 

 minatus.

Greenhouse Difficulties. — /. R. Tipperary. — 

 A variety of causes wiU induce the spot in 

 geraniums, more particularly a want ot firm- 

 ness in the soil in which they are potted, and in- 

 sufficient drainage, excessive gorging with arti- 

 ficial stimulants, such as guano or ammonia, will 

 also occasion it. Pot in two-thirds good loam, 

 one-third good rotten dung, one-sixth ailver- 

 sand, and use pounded oyster-shell for drainage. 

 Ventilate according: to the sttte of the external 

 air, and it is a hundred to one if you are 

 again troubled with spot. LiUum giganteum
