Congressional hog caller. Washington, D.C. June 9. The Capitol Plaza reverberated with sounds of the barnyard today as Rep. Robert L. Mouton, of Louisana, went into serious training for his coming hog. calling contest with Rep. Otha D. Wearin, of Iowa. The contest, which will take place on the Capitol steps sometime in the new future, is the result of an argument between the two solons as to the abilities of the hog-yodelers from the respective states.
