st be taken into consideration, as well as
the advancement in manufacturing, etc. If the invention belongs to that
class of inventions which may be generally adapted in all States alike,
such as domestic articles and articles of wearing apparel, then the
population will form a very satisfactory basis for valuation.

There are other inventions, however, that apply almost wholly to a
certain section of the country, while still others apply more to one
section than to another; thus, for instance, mechanical contrivances of
the higher order, such as writing machines, mathematical instruments,
etc., the North and East are the most valuable; for mining and
agricultural implements, etc., the West; while such as the cotton-gin,
seeders, and presses apply almost wholly to the South. States and
counties having large cities and large towns are also usually more
valuable than other States and counties of same population.

[Sidenote: Valuation Tables.]

The following tables are given as a general estimate of the relative
value of the different States and divisions in the majority of cases;
however, these tables are only arbitrary at best, and cannot be applied
to all classes of inventions satisfactorily, though they may serve to
materially aid the patentee in determining what price to put upon each
State in his own case. Having determined the value of the patent as a
whole, the aggregate of the State prices should be about two-thirds
more, as there are always some States that cannot be sold separately,
while others may have to be sold at a discount.
