remain to tliis day, and may perliaps continue two or three centuries 
longer ; some few of them have been scathed by Hghtning. There 
are calculated to be seven thousand three hundred and sixty acorns in 
bushel. In the New Forest, Evelyn counted in the sections of some 
trees, four hundred concentric rings, or layers of wood, each of which 
nmst have recorded a year's growth. 
The Turkey Oak in many situations is more profitable than 
those of our own country. The Duke of Tuscany 's princely domain 
at Pisa, is partly overgrown with woods of evergreen oak, (Quescus 
Ilex,) to which the situation is so congenial, that many of them mea- 
sure twelve feet in circumference, and the shade of single trees is 
found to be seventy or eighty feet broad ; the foliage is small of a 
dull dark green, and the aconi when roasted is palatable. 
Although the Teak Tree (Tectona grandis) is a tree of quite a 
ditferent family from the oak, and a native of India, it is used iu 
ship-building like the oak, and has some resemblance to it in its tim- 
ber. It is a tree of uncommon size, with leaves twenty inches long 
and sixteen broad, and bears a hard nut. Besides its value as timber, 
the teak has beauty as a tree ; it is found more than two hundred feel 
high, and the stem, branches, and leaves are all very imposing. 
The Aeele Tree (Populus alba) is a tree of extremely quick 
growth, and is equal to the best mahogany in colour and smoothness 
of surface ; and much superior to the Plane, or inferior sorts in those 
respects, as well as transparency and variety ; and it has the finther 
advantage over mahogany and most other woods, that it takes but 
little oil or rubbing, to produce upon it that sort of mellow shining 
surface so much admired in furniture, that it has been some years 
subject to proper attention.

Your correspondent "G. I. T." (p. 441 ) with the aid of the ingenious 
president of the Horticultural Society, has shewn how the enonnous 
quantity of 670 bushels of potatoes, of 801bs. to the bushel, may be 
produced in one statute acre of land. Will you give me leave, with
