In addition to its ,constitutional, power to "declfre: War,"
Cogress also has express power to levy, taxes and to iappropri-

States." While the scope of these powers asithey relate to

the 1936 Ashwander case casts some light on the subject. ,

the Wilson Dam at Muscle Shoals on the Tennessee River was
begun in 1917 and completed in 1926.
Taking judicial notice of he international situation in 1916,
the Supreme Court concluded that the Wilson Dam and power
plant are "adapted to the purposes of national defense."
Moreover, the Court found ample support for the District
Court's finding that, while there was no intention to use the
nitrate plants or hydroelectric units for production of war ma-
terials in time of peace, the maintenance of those properties
in operating condition and "the assurance of an abundant sup-
ply of electric energy in the event of war, constitute national
defense assets." "' And after discussing the exercise of com-
merce authority involved," the Court then made plain its ap-
proval of the construction as an exercise of both the war and
commerce powers, saying:'3

exercise of the federal commerce and war po~wea The
