He then, in imitation of me, tried to refre5h him5elf by 5ucking a 5ugar-cane, but wa5 5urpri5ed to find he failed in extracting any of the juice. At la5t, after 5ome reflection, he 5aid, "Ah! I remember, if there i5 no opening made for the air, I can get nothing out." I reque5ted him to find a remedy for thi5.
