season will be prolonged until December, or even till February. 

 M. Link observed that the truffle has a number of whitish 

 arteries, which, seen through a magnifying glass, appear to 

 consist of small cells containing kernels. It is, however, not 

 yet known how these kernels or seeds come forth, and occa- 

 sion the multiplication of the root. Another fungus, growing 

 under ground, the substance of which becomes, after it is 

 decayed, like powder, is sometimes mistaken for the truffle ; 

 but in quality they are very different. 



[Doo-s, not pigs, are employed in England to scent out 

 truffles. The man, who obeys the dog's indications, sometimes 

 rewards him for every discovery by imparting to him a por- 

 tion of some preparation of cheese ; at least, this was the 

 good fortune of a little dog expert at hunting truffles, which, 

 some years since, was kept on the estate of Lord Braybroke, 

 at Audley End, Essex. — J. D.~\

9. On Qu&cus coccinea and Q. rubra. By M. Schoch, Head- 

 Gardener at Worlitz. 



The first of these trees has been known for upwards of 

 fifty years in the park at Worlitz ; and specimens are there 

 to be found upwards of 1 00 ft. in height. There are also four 

 distinct varieties of the species coccinea, differing in the colour 

 of their leaves, and in their greater or less productiveness 

 of acorns. All of them are remarkably ornamental, from 

 the deep red of their very late falling leaves, especially in 

 autumn, and when the trees appear among the dark foliage 

 of pines. The timber is extremely firm and tough ; and so 

 suitable for furniture, that, when varnished, it becomes as dark 

 as mahogany. Quercus rubra does not form so large or so 

 handsome a tree as the scarlet oak ; but it is still very beauti- 

 ful, and deserves a place in every plantation. It requires 

 rather a moist soil.
