it ; but, in the case in question, your friendship for me has induced you to go 

 beyond the limits of my exertions in this country ; and my feehngs were 

 sensibly affected at the perusal of your article in the Gardener s Magazine for 

 October, which prompted me to write to you on the 21st of October. But, 

 dear Sir, as you in your answer to my letter will not give me leave to print 

 any of your letters in our papers, I take hereby the liberty to address you 

 again, in order to find a proper way of clearing mistakes. 



" At different preceding periods, I have written to you, dear Sir, about the 

 state of our gardening in Denmark, inserted in your Gardener'' s Magazine for 

 July, 1826 J September, 1827 5 January, 1828; October, 1829, &c. Several 

 great improvements have certainly taken place since that period, some of 

 which I take the liberty to state, as well as several errors concerning 

 gardening in this country inserted in the Gardener''s Magazine for October 

 this year. 



" 1 have introduced into this country the mode of heating hot-houses by 

 hot water in cast-iron pipes and boilers. Mostly all the houses for fruit and 

 flower-forcing in this garden are worked by hot water ; and in several of the 

 royal, and some private, gardens, about in the country, this mode of heating 

 is now introduced, and I expect it will soon be quite general. 



"A better and proper construction of forcing-houses, similar to those erected 

 in England, and some aired by ventilators in front and back, I have got built 

 and introduced. 



" The culture in general, principally in the forcing department, is much 

 improved in this garden : e. g., we have had the first ripe grapes in the 

 beginning of May ; peaches, double montagne, by the end of May ; cut 

 ripe pines almost all the year round. The hot-bed forcing equally early. 

 I have introduced nearly all the sorts of pine-apples grown in England ; 

 strawberries, Grove End scarlet, Knevett's pine, new scarlet pine, scarlet 

 emperor, and new pine : all the Chinese chrysanthemums, some of the best 

 English gooseberries ; several good green-house, and some stove, plants ; 

 dahlias, many of the best and rare varieties, &c. &c. 



" I have not established the present Floricultural Society; but, having the 

 honour of being a member, and, having for the last eighteen months, had the 

 inspection of their garden, I have done in this respect every thing in my 

 power, in a sensible way, to go on with improvements. At present, the 

 Society has bought a piece of ground for a new garden ; but, not finding it 

 answering the purpose, and, in view of economy, being of a different opinion, 

 I have resigned my situation in the present Floricultural Society. That 

 Society has given very much impulse to a better taste and improvements, 

 for a better culture of flowers during its establishment, especially by intro- 

 ducing many new and good plants. 



" The vegetable and fruit market at Copenhagen is, indeed, at all times in 

 the year, as well supplied as any one can wish for in this country ; but it is 

 not from any merit of mine. 



" Thus far the necessary explanations. You will, no doubt, dear Sir, 

 wonder at my intruding upon your leisure on this seemingly trifling occasion; 

 but you will, perhaps, give me right, when informed that I find myself in 

 duty bound to it, by a publication in one of our newspapers of your October 

 article for Denmark, which has been translated, and accompanied by low 

 acrimonious observations on it I suppose, by a youth utterly destitute of 

 knowledge in our profession; which publication, if not met with an adequate 

 answer, would present me to my countrymen in a light I do not think I 

 deserve, as my former relations to you on gardening in this country bear the 

 best witness. I am, dear Sir, &c. &c., — J. P. Petersen. Copenhagen Royal 

 Gardens, Rosenbiirg, Dec. 26. 1837."
