from an
'Introductory Address' delivered by Mr. Walker before the National
Institute, at Washington, D. C., giving a short account of the
various improvements and discoveries made by our countrymen in the
Inductive Sciences. As showing to England what a high rank we had
even then taken in the world of science, and pointing out to her
the number and fame of our savants, it will be read with just pride
and interest. As the Address was delivered in 1844, it of course
contains no details of our marvellous progress since that date in
science and discovery.--ED. CONTINENTAL.]

We have seen by the Census Tables, if the product _per capita_ of the
Slave States in 1859 had been equal to that of the Free States for that
year, that the ADDITIONAL value produced in 1859 in the Slave
States would have been $1,531,631,000. Now as our population augmented
during that decade 35.59 per cent., this _increased_ value, at that
ratio, in 1869 would have been $2,052,332,272. If multiplying the amount
_each year_ by three only, instead of 3-559/1000 the result, during that
decade, would have been as follows:

Product of 1860, $1,559,039,962
" 1861, 1,605,811,060
" 1862, 1,654,085,391
" 1863, 1,703,707,952
" 1864, 1,754,819,198
" 1865, 1,807,464,773
" 1866, 1,861,688,716
" 1867, 1,917,539,377
" 1868, 1,975,065,558
" 1869, 2,034,317,524

Total augmented
product of the $17,873,539,511
decade

That is, the total _increased_ product of the Slave States, during the
decade from 1859 to 1869, would have been $17,873,539,511, if the
production in the Slave States had been equal, _per capita_, to that of
the Free States. This, it will be remembered, is gross product. This, it
will be perceived, is far below the actual result, as we can see by
comparing the real product of 1869, $2,052,332,272, as before given,
with the $2,034,317,524, as the result of a multiplication by three each
year.

The ratio of the increase of our _wealth_, from 1850 to 1860, as shown
by the census, was much greater than that of our population--namely,
126.45 per cent. Multiplying by this ratio (126.45), the result would be
an _additional_ product in 1860, in the Slave States, of $3,427,619,475.
But our wealth increases in an augmented ratio during each decade.

Thus, the ra
