We made the usual trip up and down the river, seated in chairs under an awning on the deck of the usual commodious hand-propelled ark; made it two or three times, and could have made it with increasing interest and enjoyment many times more; for, of course, the palaces and temples would grow more and more beautiful every time one saw them, for that happens with all such things; also, I think one would not get tired of the bathers, nor their costumes, nor of their ingenuities in getting out of them and into them again without exposing too much bronze, nor of their devotional gesticulations and absorbed bead-tellings.
