Bart recognized the last speaker as Dale Wacker, a nephew of Lem. He had noticed a little earlier his big brother, Ira, a loutish, overgrown fellow who had gone around with his hands in his pockets sneering at the innocent fun the smaller boys were indulging in, and bragging about his own especial Fourth of July supply of fireworks which were to come from some mysterious source not clearly defined. The Wacker brothers belonged to a crowd Bart did not train with usually, but as Dale espied him and seized his arm energetically, Bart did not draw away, respecting the occasion and its courtesies.
