in Thoreau’s Journal:

All these birds do their warbling especially in the still, sunny hour after sunrise, as rivers twinkle at their sources. Now is the time to be abroad and hear them, as you detect the slightest ripple in smooth water. As with tinkling sounds the sources of streams burst their icy fetters, so the rills of music begin to flow and swell the general quire of spring. Memorable is the warm light of the spring sun on russet fields in the morning.

A new feature is being added to the landscape—and that is expanses of & reaches of blue water.
