Weekend fires damage Fraternity,Krogers A fire broke out on the second floor of the Zeta Beta Tau fraternity house, 1144 La., at 2:27 p.m. Friday. An estimated $800 damage occurred as a double-decked bed and mattresses were destroyed. Damages to the building were estimated at $300; to contents at $500. Firemen have not yet determined the cause. Another fire reported at 4:21 a.m. Saturday at Krogers Downtown, 844 N.H., caused an estimated $300 damage to the building and is under investigation by deputy Kansas fire marshal, Lloyd Davies. Cause of this fire also has not been determined. John Hawkins, Kansas City, Mo., security guard who was locked in the building overnight reported the fire. Hawkins used a shotgun to break out the front door of the building, so that Lawrence firemen could enter the firm and extinguish the fire. The fire started in a broom closet according to the report made by Hawkins to fire marshal Davies. He thought he had extinguished the fire before he called the headquarters of his firm. He then returned to the fire area near the central part of the building and found the blaze larger than when he first noticed it. According to the report, Hawkins then called headquarters for the second time and was told to call the fire department.

He said the total overtime cost for this hour total reached $21,171.69, with B&G earning $12,950.25 for 170 persons working 3,125 hours; the dormitory system earning $102.33 for five persons working 22 hours, and the Traffic and Security earning 14 KANSAN May 11 1970 $6,900 for 23 persons working 1,106 hours.
