We that acquaint ourselves with every zone,
And pass the tropics, and behold each pole;
When we come home, are to ourselves unknown,
And unacquainted still with our own soul. [ Davies ]

A loving heart carries with it, under every parallel of latitude, the warmth and light of the tropics. It plants its Eden in the wilderness and solitary place, and sows with flowers the gray desolation of rock and mosses. [ Whittier ]
