Section 29, Laws of South Dakota, 1909, c. 240, which forbids
shipment by carrier of wild ducks and is applicable whether the
birds were taken lawfully or unlawfully, or shipped in open or
closed season, is not inconsistent with the Federal Migratory Bird
Act of March 4, 1913, c. 145, 37 Stat. 828, 847, and the
regulations of the Department of Agriculture adopted thereunder,
since the latter act prohibit
Page 250 U. S. 119
only the destruction or taking of birds contrary to the
regulations, and the regulations merely prescribe the closed
season, and neither the act nor the regulations deals with
shipping. P.

Whether other provisions of this state law may be in conflict
with the federal act is not considered, since the provisions in
question may stand alone.
Id.
The declaration of the federal act that the migratory birds
"shall hereafter be deemed to be within the custody and protection
of the government of the United States" is limited by the context
to the prohibition above stated. P.

The case is stated in the opinion.
MR. JUSTICE BRANDEIS delivered the opinion of the Court.
By the federal Migratory Bird Act (Act March 4, 1913, c. 145, 37
Stat. 828, 847), Congress provided that:
"All wild geese, wild swans, brant, wild ducks, snipe, plover,
woodcock, rail, wild pigeons, and all other migratory game and
insectivorous birds which in their northern and southern migrations
pass through or do not remain permanently the entire year within
the borders of any state or territory shall hereafter be deemed to
be within the custody and protection of the government of the
United States, and shall not be destroyed or taken contrary to
regulations hereinafter provided therefor."
These regulations relate to the fixing of "closed seasons,
having due regard to the zones of temperature, breeding habits, and
times and line of migratory flight." The act further declared
that
"nothing
Page 250 U. S. 120
herein contained shall be deemed to affect or interfere with the
local laws of the states and territories for the protection of
nonmigratory game or other birds resident and breeding within their
borders, nor to prevent the states and territories from enacting
laws and regulations to promote and render efficient the
regulations of the Department of Agriculture provided under this
statute."
Regulations were proclaimed October 1, 1913, 38 Stat. 1960, and
were amended by the proclamation of August 31, 1914, 38 Stat. 2024,
and the proclamation of October 1, 1914, 38 Stat. 2032.
Before the passage of the federal law, the Legislature of South
Dakota had provided (Laws 1909, c. 240, § 29), that:
"No person shall . . . ship, convey or cause to be shipped or
transported by common or private carrier, to any person, either
within or without the state, . . . wild duck of any variety. . .
."
For violation of this statute by shipping on November 19, 1915,
by express, wild ducks from a point within the state to Chicago,
Illinois, Carey was prosecuted in a state court. He insisted that
the state statute had been abrogated by the federal law. The
contention was overruled, and he was convicted by the trial court.
Its judgment was affirmed by the supreme court of the state
(
State v. Carey, 39 S.D. 524). The case comes here on writ
of error under § 237 of the Judicial Code.
It is admitted that, in the absence of federal legislation on
the subject, a state has exclusive power to control wild game
within its borders, and that the South Dakota law was valid when
enacted, although it incidentally affected interstate commerce.
Geer v. Connecticut, 161 U. S. 519;
Silz v. Hesterberg, 211 U. S. 31. The
contention made by Carey is that Congress assumed exclusive
jurisdiction over this class of migratory birds by the 1913 act;
that then-existing state laws on the subject were thereby abrogated
or suspended; that the power of the states to legislate on the
subject was limited to such subsequent
Page 250 U. S. 121
enactments as were designed to render more effective regulations
issued by the Department of Agriculture, and that the statute in
question was obviously not of that character, both because it
antedated the federal act and because the regulations issued under
the federal act permitted the killing of wild ducks in South Dakota
between September 7 and December 1, during which period the wild
ducks shipped on November 19 had presumably been killed. On behalf
of the state, it was contended that this provision of its statute
is not inconsistent with the federal law, and that its statute is,
in any event, valid because the federal law is unconstitutional.
United States v. McCullagh, 221 F. 288. The Supreme Court
of South Dakota did not pass upon the constitutional question, but
upheld the state statute on the ground that it was not inconsistent
with the federal law, since it did not appear that the ducks in
question had been killed in violation of any regulation adopted
under it.
The prohibition of the federal act is limited to the provision
that the birds "shall not be destroyed or taken contrary to
regulations." The regulations merely prescribe the closed seasons
-- that is, neither the federal law nor the regulations deal with
shipping.
* The prohibition
of the state law here in question is limited to forbidding persons
to "ship . . . by common or private carrier." It applies alike
whether the shipment is made in open or closed season, and it
applies although the birds were lawfully killed or taken. This
provision of the state law is obviously not inconsistent with the
federal law. The fact that other provisions of this state statute
may be so (which we do not consider) is immaterial, as the
provision here in question may clearly stand alone.
Brazee v.
Michigan, 241 U. S. 340,
241 U. S. 344;
Guinn v. United States, 238 U. S. 347,
238 U. S. 366;
Louisville & Nashville
Railroad Co. v.
Page 250 U. S. 122
Garrett,
231 U. S. 298,
231 U. S. 311;
Presser v. Illinois, 116 U. S. 252,
116 U. S.
263.
It is, however, urged that Congress has manifested its intention
to assume exclusive jurisdiction of the subject, and that the
failure to make any provision in the federal act concerning
shipping evidences the purpose of Congress that the shipping of
game birds shall not be prohibited. This argument rests upon the
clause which declares that the migratory birds "shall hereafter be
deemed to be within the custody and protection of the government of
the United States." But that clause may not be read without its
context, and the words immediately following show that the custody
and protection is limited to prohibiting their being "destroyed or
taken contrary to regulations" which are to fix the closed seasons
in the several zones. If, reading the federal act as a whole, there
were room for doubt, two established rules of construction would
lead us to resolve the doubt in favor of sustaining the validity of
the state law.
First. The intent to supersede the exercise
by a state of its police powers is not to be implied unless the act
of Congress fairly interpreted is in actual conflict with the law
of the state.
Savage v. Jones, 225 U.
S. 501,
225 U. S. 533;
Missouri, Kansas & Texas Ry. Co. v. Haber,
169 U. S. 613,
169 U. S. 623.
Second. Where a statute is reasonably susceptible of two
interpretations, by one of which it would be clearly constitutional
and by the other of which its constitutionality would be doubtful,
the former construction should be adopted.
Harriman v.
Interstate Commerce Commission, 211 U.
S. 407,
211 U. S. 422;
Knights Templars' Indemnity Co. v. Jarman, 187 U.
S. 197,
187 U. S.
205.
The Supreme Court of South Dakota did not err in its judgment
unholding the constitutionality of the provision of the state
statute under which the plaintiff in error was convicted, and its
judgment is
Affirmed.
* The Migratory Bird Treaty Act (Act July 3, 1918, c. 128, 40
Stat. 755) deals in § 4 with shipments in interstate commerce.
