The real Double Cowslip, in answer to the Rev. W. T. Bree of Allcsley 

 Rectory (Vol. IV. p. 446.) — J. B. Ward, Esq., of Mount Pleasant near Shef- 

 field, states that he is in possession of the real double cowslip, not the cowslip 

 with a twofold corolla, hose in hose as it is termed, but with a fine double 

 blossom. " I do not believe any person in our neighbourhood is in the pos- 

 session of this singularly beautiful plant, except myself. I have bloomed it 

 for many years. I remain, Sir, &c. — S. B. Ward. Feb. 23. 1829." 



Maggots m Celery. — The maggots noticed by J. F., of Battersea (Vol. 

 IV. p. 100), have again made their appearance in great numbers on, 

 or rather in, the leaves of the celei-y. They first appeared on the 10th of 

 September, and, in a short time, tne celery bore the appearance of being 

 sprinkled over with boiling water. There being slight frosts, with cutting 

 easterly winds, about that time, many attributed it to that, little sus- 

 pecting that each leaf contained an insect, and that each decayed leaf was 

 the effect of its ravages. — J. H. Dec. 12. 1828. 



Destroying Woodlice (in answer to Z., Vol. III. p. 381.). — Sir, Of all the 

 insects that infest cucumber frames, I know none worse than woodlice, I 

 tried several things, as sulphur, lime, and soot, for the purpose of destroying 

 them ; but none of these were available. At last I thought of a scheme 

 which perfectly answered the purpose. I pressed the mould very tight and 

 closely all round within the frame, making a kind of trough about six 

 inches wide. This I covered with hay about two inches thick, which I 

 expected would form a retreat for the insects. They soon collected there, 

 and were destroyed by pouring boiling water over the hay. This I repeated 

 till I got rid of all the insects. This plan of inviting the woodlice toge- 

 ther and scalding them to death, is adopted when the cucumber plants are 

 young; and it may be necessary to add, that this application of water does 

 good rather than harm when there is a strong heat in the bed, but is not quite 

 so suitable when the heat is on the decline. I am. Sir, yours, &c. — J.N. 

 a Gentleman's Gardener. Jan. 27. 1828. 



Methleys Fire-places. (Moser & Co.) — Have you seen any of Moser's 

 fire-places, and are you aware that they not only throw out more heat 

 than any elegant chamber-stove hitherto in use, but also, by means of cer- 

 tain small holes in the back and sides, burn great part of the smoke? 

 Might not hot-house furnaces be constructed on a similar principle so as to 

 burn the smoke, or a part of it, and thus procure more heat from the same 

 quantity of fuel, and save the troublesome and disagreeable operation of 

 sweeping the flues ? — S. B. Bristol, March 4. 1829. 



We are fully aware of the superior excellence of Methley's stoves (of 

 the firm of Moser and Co. of Frith Street, furnishing ironmongers), for 

 rooms, an eminent architect in this neighbourhood having them in every 

 room of his house, and having ourselves one. We have little doubt the 

 improvement might, to a certain extent, be added to hot-house furnaces, 

 but we believe it has not yet been so applied. — Cond. 



Errors in the EncyclopcBdias of Gardening and Agriculture. — Sir, Would 

 it not be wise to request your correspondents that they would generally 

 communicate to you any error, especially in the statistical details of your 

 Encyclopaedias, that may happen to have come under their notice. This 

 would much improve them for a future edition, and would be generally a 

 public good. — J. S. L. CI — n, December 9. 1828. 



We have done so in the prefaces to these works, on the covers of the 

 earlier Numbers of this Magazine, and again do so. We are most anxious 

 to receive every description of correction, and no correspondent can oblige 

 us more than by pointing out errors in these works, in this, or in any other 

 in which we are engaged. — Cond. 



Smoky Chimneys, — I wish you to touch upon the subject of chimneys, a 

 subject which I believe to be very well understood by a few, but by the
