ut there is an army of prisoners in every
state, whose labor is so directed, and has been so directed for
generations past, that it adds little or nothing to the common wealth.
The labor of these prisoners, properly applied and directed, would be of
great benefit and improvement to the highways, and would add greatly to
the national wealth, while at the same time it would lighten the
pressure of competition with free labor by withdrawing the prison labor
from the manufacture of commercial articles and applying it to work not
now performed, that is, the building of highways or preparing material
to be used therefor.
The General Government, having withdrawn from the field of road
construction in 1832, has since done little in that line until very
recently. Eight years ago Congress appropriated a small sum of money for
the purpose of instituting a sort of inquiry into the prevailing
condition of things pertaining to road matters. This appropriation has
been continued from year to year and increased during the last two years
with a view of cooperating to a limited extent with other efforts in
road construction.
The General Government can perform certain duties pertaining to
scientific road improvement better than any other agency. Scientific
facts ascertained at one time by the General Government will serve for
the enlightenment of the people of all the states, and with no more cost
than would be required for each single state to make the investigation
and ascertain the facts for itself.
With a view to securing scientific facts in reference to the value of
road-building materials, the Secretary of Agriculture has established at
Washington, D. C., a mechanical and chemical laboratory for testing such
material from all parts of the country. Professor L. W. Page, late of
Harvard University, is in charge of this laboratory, and has tested many
samples of rock without charge to those having the test made. There is,
however, no test equal to the actual application of the material to the
road itself.
With a view to making more extensive tests than could be done by
laboratory work alone, the Director of the Office of Public Road
Inquiries has, during the past two years, cooperated with the local
authorities in many different states in building short sections of
object-lesson roads. In this work it is intended not only to contribute
something by way of cooperation on the part of the General Government,
but also to secure co
