NOTICES TO CORRESPONDENTS. 



An Old Subscriber. — Salo}). — Seed of the second plant on your list is not, so 

 far as we are aware, plentiful in the trade. See answer to Mr. Cooper in the March 

 number at page 95. With respect to the other matter, write to Mr. Cann2ll, 

 Woolwich. 



C. M. — We do not know of any firm who devote especial attention to the subjects 

 mentioned in your letter, or wa should have been glad to have assisted you. 



Kainit and Superphosphate. — G. K., Parrickmacross, Ireland.— -Mix. in 

 equal proportions, and apply at the rate of 7 cwt. per acre. The letter was too late 

 tb admit of its being answered last month, and we cannot make any exceptions to 

 our rule of not answering correspondents privately. 



Potatoes on Tiles. — Clericus Hortensis. — The method of growing potatoes 

 is fully explained in the Floral World for February 1869. We regret the answer 

 was accidentally omitted from last month's number. 



Tan. — G. K. P., Worcester. — Tanners' bark may be employed for making hot- 

 beds for the cultivation of cucumbers during the summer, but it must have the aid 

 of a few boards round the outside of the bed to keep it up. It would be a good 

 plan to have the bed partly below aud partly above the surface. Take out the soil 

 to a depth of two feet, and the same size as the frame. Then drive in four stout 

 stakes, one at each corner, to support the frame at a height of about two feet 

 above the level. Nail rather stout boards to the uprights, and as soon as the frame- 

 work is completed, the tan can be put in and the frame put upon the uprights. Tread 

 the tan firmly, and allow a few days for it to settle before putting on the soil. After 

 the frame is in position, a few barrowfuls of tan, sufficient to reach from six to 

 twelve inches above the lower edge of the wood, should be added. 



Propagating Cases. — S. F. S. 8., Dublin. — Miss Maling's plant case is manu- 

 factured by Mr. Gray, Horticultural Works, Danvers Street, Chelsea, London. We 

 figured and described an excellent case in the Floral Would for August, 1870, 

 which is manufactured by Messrs. Barr and Sugden, 12, King Street, Covent 

 Garden, W.C. 



Date of Show. — TV. Brown, Carmarthen. — The first or second week in August 

 would be suitable for holding a horticultural exhibition principally supported by 

 amateur growers. No matter what the date of the exhibition may be, it will be 

 too early for some of the exhibitors, and too late for others. 

 Name of Fern. — D. M. — Adiantum iEthiopicum. 



Destroying Cockroaches, Crickets, and Woodlice. — An esteemed cor- 

 respondent, resident at Halifax, sends the following particulars respecting these 

 pests. He says, " Between three and four years ago I entered the house I am now 

 residing in, which was then quite new. A short time after we took possession, the 

 cockroaches made their appearance, and were soon followed by crickets, which 

 I thoroughly detest. We at once took measures for their extirpation, and happen- 

 ing to hit upon the right method, we did not have so much trouble as we antici- 

 pated. We commenced by putting down a few white shallow pots, such as are 

 used for potted fish and meats, and then half-filled them with water and treacle. 

 This mixture settled the cockroaches, but the crickets skimmed about on the surface 

 like so many water-spiders. Treacle alone was then employed, which held them 

 fast enough. The whole surface was covered, and then we turned up the pots, and 

 brushed them into a vessel of boiling hot water. As a rule, we emptied them every 

 morning. The same plan was also tried with woodlice, and, I am happy to say, 

 with the moet satisfactory results. We have now completely cleared the house of 

 every one of these pests, and the trouble has been so small, that really it is not 

 worth mentioning. Treacle is known in some parts of the country as molasses, 

 and the ordinary price is from two to three pence per pound. I feel assured that if 

 those who are bothered with either or all of these pests adopt the method here 

 described, they will not regret having done so." 



Begonia fuchsioides for Flowering in Autumn. — John Harris. — Most 

 certainly this fine begonia can be flowered in the autumn. Several years since, we 

 used to have it very fine in the autumn months, and always managed it as fol- 

 lows : — cuttings were put in in April, and grown on liberally all the summer in the 

 stove, and kept moving all the next winter, and the following spring until June,
