As an ass1 was quietly dining on thistles，he beheld2 a shepherd seated beneath a tree，awakening sweet echoes on his flute3，and charming the ears of all within hearing，excepting our discontented lop-eared brute，who thus soliloquized：“The world is going mad！Be-hold all the people admiring，with open mouths，a fool who is straining and puffing4 himself into a perspiration5 with blowing into a little hollow tube．So easily are mankind pleased，while-but no matter．Let me hasten out of the fool's hearing．I shall go mad．”
As our scandalized ass was moving off at a brisk canter，he presently almost kicked against a flute，which chanced to have been left on the turf by an amorous6 shepherd．The ass stopped，gazed knowingly round，and contemplated7 the flute as it lay；slowly he lowered his head，and placing his under lip on the mouth-hole，he blew in- to the despised instrument，when，mirabile dictu，it yielded an agree- able sound．Our ass thought himself a clever fellow，and cried aloud，as he kicked his hind8 legs in the air with joy，“Bravo！I too can play on the flute！”
