The prize was delivered to tom with as much effusion as the superintendent could pump up under the circumstances ; but it lacked somewhat of the true gush, for the poor fellow s instinct taught him that there was a mystery here that could not well bear the light, perhaps ; it was simply preposterous that this boy had warehoused two thousand sheaves of scriptural wisdom on his premises - a dozen would strain his capacity, without a doubt
