opinion: Per Curiam.
  When the validity of a state statute, challenged under the United States Constitution, is properly for adjudication before a United States District Court, reference to the state courts for construction of the statute should not automatically be made. The judgment is vacated and the case is remanded to the United States District Court for the ^Eastern District of Arkansas for consideration in light of Harrison v. N. A. A. C. P., ante, p. 167.
