Captain  Says  Amateurs  Interfere  With  Wireless

    "Our wireless was interfered with constantly by amateurs while we we searching for the Republic," said Capt. K. W. Perry of the revenue cutter Gresham Wednesday night.
    "We have long felt the necessity for some regulation in the use of wireless outfits, but the imperative need of such regulation has been demonstrated in the experiences of the past few days. We were given four different locations of the crippled steamship, to all of which we went.
    "At last I telegraphed the department at Washington. The reply was delayed 12 hours, and the delay was caused by sending private messages and the interference of amateur operators."
