69daily and then having no assurance that relighting was accomplished. In order to verify the conditions that existed in connection with this situation, visibility tests were made on all ten buoys twice each day without the use of control equipment. A tabulation sheet showing all ten controlled buoys, the date and hour, an indication of each buoy light that was visible before 0800 and after 1200 each day was submitted to the District Coast Guard Office weekly. In 3920 observations, lights were visible by telescope from Cape Disappointment Lookout Station only 2900 times. This figure included all ten buoys listed on the previous page, during period from 17 July, 1944, to 12 February, 1945, at which time the visibility tests were discontinued. By November, 1944, Headquarters became interested in the peace time value of ANRAC and requested that the District Coast Guard Officer prepare a list of such locations in the 13th Naval District where ANRAC could be used for peace time operation. The major complicated features (essential for security) were to be simplified to meet peace time application to unattended radiobeacons or fog signals where maintenance by an operating crew and expenses related thereto presented objectionable difficulties. In response, the District Coast Guard Office listed five fog signals near the mouth of the Columbia River within a three mile radius from Point Adams Lifeboat Station, Hammond, Oregon, and the fog signals at Tacoma Waterway, Milwaukie Shoal and Point Defiance all within a radius of 4 1/2 miles of Browns Point Light near Tacoma, Washington. However, the District Coast Guard Officer did not feel that ANRAC control of shore lights during peace time would have any advantage over the sun relays currently installed due to the higher cost and a greater possibility for human error. Headquarters was requested, since the war time ANRAC program had proved unsatisfactory, that authority to discontinue the radio control of the lights on the buoys at the entrance to the Columbia River be granted.
