This will be clearly understood from the view dated October31st, Fig. 12, which shows the reinforcement and forms ready forpouring the concrete. The remaining views are explained by theiraccompanying legends. The diagram of loaded areas for the mushroom slab Fig. 13. islike that already given for the Norcross slab in every particularexcept that the size of the mushroom slab being 18 x 18, while theNorcross slab was 16 x 16, the arms of the Gnn^k cross in thenmshroom slab are each 5 6 lonsr and 5 wide. 84 LOADS ON NORCROSS SLAB o ft 5q oo 02 o O CO03 ^ 13o (M (M CO (M CSI(M (M ^ (M (MCO CO lO CO COO O ^ O OC^ CQ CO (M (M COCO00(M T—1T—1 persq. ft.
