Joseph Jessop, noted archery expert, whose exhibit of bows and arrows in the museum is one of the finest in America, has offered to assist in the forming of Thunderbird archery clubs, and these will hold Robin Hood contests at the desert. A shop will be installed where the boys can make their bows and arrows besides other crafts products. There will be music, games and a jousting tournament or tub-tilting between teams to be fought out during four Saturdays with prizes. Other details of the lively program will be worked out at a meeting between Chief Marsh and sub-chiefs at the Grant hotel tonight. Many of the Woodcraft contests will be a continuation of those illustrated by Seton last Saturday to the delight of over 3,000 kiddies and their friends at the reopening of the desert to the public.
