A new intermediate landing is now in operation 2 miles north of Streator (lat. 41° 10': long. 88° 50'). This new field is L shaped, with an available triangular tract at the Junction of the runways, which are: North-south, 2,250 feet; east-west. 2,617 feet; northeast to southwest, approximately 2,000 feet. Approaches to the field from the north and west are free from obstructions. Approach to the east-west runway from the east is obstructed by trees, farm buildings, and a pole line which is marked with red lights. Approach to the north-south runway from the south is obstructed by trees which are to be cut in the near future. At present these trees are unmarked. A 24-inch 2,000.000 candlepower beacon is mounted on a 62-foot tower in the southeast corner of the east-west runway. The elevation of the main beam of this light, which shows six rotations per minute, is 1 ¾ ° above the horizon. At the base of the tower a concrete directional arrow has been established, the bearings of which are: Forward 57° azimuth true, 54° azimuth magnetic; backward 237° azimuth true. 234° azimuth magnetic. The day marking of this field consists of: A 50-foot yellow circle with two arms located at the Intersection of the runways: metal cones painted yellow and mounted on all boundary lights outlining the field; border strip markers painted yellow installed at all corners and also at intervals of approximately 1,000 feet along the boundary lines of the field. An illuminated wind cone is mounted on the beacon tower. For night flying, boundary lights outline the field and green approach lights indicate the best runways. The route designation "SL-C " and the number " 20" are painted on the roof of the power shed at the base of the tower. Green course lights mounted on the tower platform flash a code: Dash, dash.
