wall, and some hot dung added. Observe, that the ends of the mats which 

 hang down in front, must be thrown up every day when it does not freeze. 

 Greenhouse plants should be housed in October, and put out either at the 

 latter end of April, or beginning of May. 



Plants that will grow in London. — R. A. M. requires a list of those 

 plants which best suit a London garden, as being least affected by its blacks. 

 I have found those which are here enumerated, best to answer the above 

 description : — 



Shrubs. Jasminum officinale, and revolutum ; Ligustrum vulgare ; Rhus 

 elegans ; Syringa vulgaris ; Prunus /auro-cerasus ; Hedera Helix; Fitls vini- 

 fera, and vulpina. 



Herbaceous plants, iinum perenne ; iVarcissus poeticus ; Crocus sativus 

 veVnus ; 5cabiosa atropurpurea ; Convolvulus purpureus, and tricolor ; Cam- 

 panula medium, and speculum ; Nolana prostrata ; Ipomce'a coccinea ; Tro- 

 pae'olum majus; Mirabilis jalapa ; Agapanthus umbellatus ; Lilium candi- 

 dum, and bulbiferum ; Oenothera biennis, tetraptera, and purpurea; iupinus 

 luteus, hirsutus, and pilosus ; Polygonum Persicaria ; Dictamnus albus ; 

 Dianthus barbatus ; Silene Armaria ; Agrost^mma coronaria ; Jdonis au- 

 tumnalis ; Helianthus annuus ; Phaseolus multiflorus ; Jberis amara. 



Caterpillars on Mignonette. — R. A. M. requires some hints and sug- 

 gestions on preventing the ravages of the common green caterpillar on 

 Mignonette. 



For this evil I can give a certain remedy. — Put some unslaked lime into 

 a pail, pour water on it, and let it stand for half an hour to settle, and then 

 pour the water on the Mignonette. It will kill any sort of caterpillar, 

 slug, or worm, if two or three times repeated, without in the least degree 

 injuring the plants. 



Cutting Flowers. — R. A.' M. enquires how to cut flowers without injuring 

 the plant. — Flowers should be cut with a sharp knife, at a joint, and par- 

 ticular care should be taken to cut clean.

Worms in the Buds. — " Mr. D. Taylor (p. 254.) complains of having the 

 buds of his fruit trees destroyed by worms. I presume he means his apple 

 and pear trees, and beg to inform him, that it is not the American blight, 

 nor any other transatlantic enemy he has to contend with, but, as I think, 

 some winged insect which produces the worms, laying the eggs, like the silk 

 insect, and, I believe, most others, the preceding autumn, on or near the 

 buds. At the time the buds are swelling, the eggs by the increased heat of 

 the sun are hatched, when they perforate the bud and produce the effect 

 complained of. The method that the farmers in this county take to destroy 

 these and other insects in their cider orchards, and which I have adopted 

 successfully in this garden, is to collect a quantity of any kind of rubbish that 

 will burn without bursting into a flame under the trees, and on a calm day 

 by setting it on fire, when a cloud of smoke ascends to every part of the 

 tree. I also sprinkle a little sulphur on the burning mass, and afterwards, to 

 make assurance doubly sure, I syringe the trees with lime-water, &c. It may 

 be proper to add, that before Mr. Taylor sees this, should you think proper 

 to publish it in the next Magazine, it may be too late in the season to 

 adopt it with success, for should the grub' once effect an entrance it will be 

 impossible to dislodge him, without pulling the bud in pieces ; the process, 

 however, may be adopted next season.
