Novelty Bone Soloist

Hayes performs on the bones with a good deal of skill, varying the monotony of the proceedings by substituting for the recognized minstrel instruments glasses, knives and forks and finally dog biscuits. The dog biscuits probably account for the term “novelty” in the billing.
Even allowing that dog biscuits are a novel medium of musical expression, it takes a pretty easy audience to get thrilling entertainment out of an act of this grade and it is hard to see where up-to-date vaudeville is beckoning to Hayes with any degree of enthusiasm.
