i" wish to burst the double yellow rose, and apply to you for some 

 assistance. For the last three years I have carefully watched a double 

 yellow rose on its own roots in my garden ; it has had the advantage of 

 being placed against a south wall of a hot-house. The first year it pro- 

 duced no buds, the second it produced four, and the third twenty-four, but 

 I have never had the pleasure of seeing a single blossom burst. As soon as 

 the calyx divides, a small insect is seen, which appears to have made the 

 bud its habitation, and to have lived upon the petals of the flower. The 

 plant has been constantly washed, and it thrives remarkably well. If 

 through the medium of your widely circulated Magazine you could suggest 

 any plan for destroying the above-mentioned insect, you will confer a great 

 obligation upon Yours, &c. — R. N. Southborough Lodge, Bromley, Kent. 



Primida sinensis. — Some hints on the propagation and culture of this plant 

 are wanted by — A Constant Reader, fyc. March 10. 



Cutting over young Forest Trees. — Having been engaged in planting 

 recently in a very chalky soil, which has been well trenched to the depth 

 of eighteen inches, and finding that the trees, excepting those of the fir 

 tribe, have in many cases seemed to flourish for the first year, and then 

 come nearly to a stand, and so seem disposed to continue, particularly the 

 ash, I would beg to ask you whether I am right in wishing to have them 

 all cut down ? how near the ground it ought to be done ? at what time 

 of the year ? whether all the sorts ought to be so treated, say oak, ash, 

 birch, beech, sycamore, elm, hazel, thorn, &c. ? whether it ought to be 

 done the first, second, third, fourth, or fifth year after planting? and whether 

 it ought to be repeated ? — W. TJionville.

The Coffee Bean, " it is generally said, loses its vitality in a few weeks. 

 Some years ago, when I resided in Italy, my children used to sow the beans 

 which we had in daily use, and they grew freely. I suppose they were im- 

 ported to Leghorn from Africa, but how old they might be I am not able to 

 say. When I mentioned this to a gentlemen curious in botanical matters, 

 he told me he had raised date and cocoa palms from nuts bought in the 

 London shops, but had never tried the Coffee. I should like to know the 

 experience of others on the subject." — C. H. D. March. Since the above 

 was in type, we have seen a young Coffee plant raised from one of a hand- 

 ful of seeds, taken indiscriminately from a parcel of Mocha Coffee purchased 

 in the shops. — Cond. 



Destroying the Green Fly on Peach Trees. — " Has any correspondent 

 tried the effect of Digitalis for this purpose ? I procured 4 oz. of tincture of 

 Digitalis, which I mixed with about 5 pints of water, and in the evening, 

 with a small brush, which I made with soft feathers, I brushed over every 

 part of a tree very much infested, with the mixture. Next day the insects 

 appeared to be dead ; in two or three days I was convinced they were so ; 

 I then took a pot of soft water and washed the tree as clean as I could ; 

 it soon after began again to produce fresh wood, and is now at the 

 time of my writing this completely filled, with the exception of one small 

 branch at bottom, with sound, firm, and healthy wood. — _D. F. July, 1826. 



Mildew. — Sir, — You will particularly oblige me, as well as a num- 

 ber of your subscribers in this part of the "country, by inserting in 

 your widely circulated Magazine the following queries, relative to that 

 hitherto incurable evil, so troublesome to gardeners, the mildew. Of this 

 evil, all gardeners have reason, more or less, to complain; and, as far 

 as I know, none have yet found out its radical cure. The questions which 

 I now solicit you to publish may, probably, by attracting the attention of 

 some of your scientific readers, be the means of eliciting from them some-
