150 Baron Hiigel' s Garden and Collection of Plants. 



&c, and here you cannot resist the old answer to the question, 

 Does it always rain ? { No, it sometimes snaws (snows).' Now, in 

 1841, we had 143 fair days, 66 cloudy, 41 stormy, 76 rainy, 41 

 showery, and 1 2 snowy. But, in as far as the fuliginous particles are 

 concerned in not injuring the trees, you are quite correct, even 

 without their being washed off, thus evidencing in some degree 

 their innocuous quality ; because upon the south'side of the river 

 even the Pinus sylvestris thrives amidst a perfect Pandemonium 

 of smoke, arising from the coal and iron-works in that neigh- 

 bourhood : but there exist no chemical factories on the south, 

 unlike in that respect the north bank of the Clyde, where these 

 exist in great number; the acidulous emanations from which, 

 even at the distance you mention, wither up the leaves in the 

 course of a few hours ; thus, during summer, the leaves of the 

 common lilac, in front of my house, fell off and were renewed 

 two or three times, or, in other words, as often as the wind 

 blew from that quarter ; eventually the twigs became dried up, 

 then the branches, and finally the trunk itself. 



" Whilst on this subject, I may mention a fact which I cannot 

 sufficiently explain upon physiological principles, and I shall be 

 glad to be gratified in your continuation in March next, viz. that 

 those plants and trees whose habitat is either alpine or maritime, 

 such as the thrift, Armeria, the saxifrages, particularly the 

 S. umbrosa (London pride), the birch, &c, flourish most lux- 

 uriantly even in the midst of those chemical emanations. — S. 

 Jan. 27. 1842." 



Probably the leaves of alpine plants may have fewer stomata 

 than those of plants which grow on plains, and hence may be 

 less affected by changes of air than those which have numerous 

 stomata. They may thus thrive in an atmosphere impregnated 

 with salt, and also in one impregnated with soot. This, how- 

 ever, is mere conjecture.

Art. II. A Description of the Garden and Collection of Plants of 

 Baron Hiigel, at Hietzing, near Vienna. By M. Maximilian 

 Peintner, Secretary to the Imperial Horticultural Society. 



(Translated from the Garten Zeitung, August 21st, 1841.) 



The zeal which the celebrated traveller and botanist, Baron Karl von Hiigel, 

 has shown for several years past in increasing his collection of plants, is truly 

 astonishing. He spared no expense in obtaining whatever was new, both 

 near and at a distance, to enrich his garden, and obtain a complete collection. 

 His efforts are now crowned with success, as he possesses at present one of
