Explanation of the C 
Tables I. and If. 
To render the preceding tables easy to 
be understood by persons not accus- 
tomed to calculations, we shall state 
the process of the operations in the first 
jine of Table IT. 
The height of the tree at 12 years ofage 
- is supposed to be 18 feet to the top of its 
leading shoot, and 24 inches in circum- 
ference at the ground, consequently, at 
half the heiglit, the circumference is 12 
inches ; one fourth of this, being three 
inches, is called the girt. ‘The girt being 
squared and multiplied into the height, 
gives one fvot one inch and six parts for 
its contents. At 13 years old, the tree 
will be 194 feet high, 26 inches in circum 
ference at the ground, and 13 inches at 
half the height; one-fourth of 13 gives 
St inch for the girt. This squared and 
multiplied into the height, gives one foot 
five inches and one part for the contents, 
Deduct from this the contents of the tree 
at 12 years of age, and there remains 
three inches and seven parts, which is the 
increase in the 13th year. Then reduce 
the contents of the tree when 12 years 
old, and the increase in the 13th year, 
each into parts, dividing the former by 
the latter, and the quotient will be 3°76; 
onstruction of 
by this number divide 100, and the que- 
tient 1s 26°5. which is the rate per cent. 
of increase made in the thirteenth year; 
consequently, whatever the tree might be 
worth when 12 years old, it will, at the 
end of the 13th year, be improved in va- 
Tue after the rate of 26/. 10s, per ceat. or 
in other words, that will be the interest it 
will have paid that year, for the money 
the tree was worth the preceding year. 
At every suceeding period, both in this 
Table and Table I. the like process is 
gone through. . 
Observations on Tables I. and 1X. 
The preceding tables furnish us with che 
following useful information, viz. 
ist. That all regular growing trees, 
measured as above, as often as their age 
is increased one-fourth, contain very 
nearly double their quantity of timber. 
2ud. That when a tree has doubled its 
age, its contents will be eight-fold. 
Sd. That when a tree has doubled the 
age, its annual growth will be- increased 
four-fold. 
4th, Consequently, that when a tree 
has doubled its age, the proportion that 
its annual increase bears to the contents 
of the whole tree, is then diminished 
one-half. 
REVIEW OF NEW MUSICAL PUBLICATIONS.

The Overture, and most admired Songs and Duets, 
in the Opera of the Circassian Bride, as per- 
formed at the late Theatre Royal, Drury Lane. 
Composed and arranged for the Piano-forte, 
or Harp, by H.R. Bishop. 8s, 
FTER a sedulous perusal of the mu- 
sic of the Circassian Bride, we are 
, 
pleased at being authorized by its merits, 
to employ in its favour, the terms of our 
warm. and unqualified commendation, 
The melodies are, in most instances, 
uncommonly select, and particularly ap- 
propriate. The expression is faithful to 
the sentiment of the author, the turns of
