March 11th.–After the ground had been completely freed of snow, there has been a snow-storm for the two days preceding yesterday, which made the earth all white again. This morning at sunrise, the thermometer stood at about 18 degrees above zero. Monument Mountain stands out in great prominence, with its dark forest-covered sides, and here and there a large, white patch, indicating tillage or pasture land; but making a generally dark contrast with the white expanse of the frozen and snow-covered lake at its base, and the more undulating white of the surrounding country. Yesterday, under the sunshine of mid-day, and with many voluminous clouds hanging overit, and a mist of wintry warmth in the air, it had a kind of visionary aspect, although still it was brought out in striking relief. But though one could see all its bulgings, round swells, and precipitous abruptnesses, it looked as much akin to the clouds as to solid earth and rock substance. In the early sunshine of the morning, the atmosphere being very clear, I saw the dome of Taconic with more distinctness than ever before, the snow-patches, and brown, uncovered soil on its round head, being fully visible. Generally it is but a dark blue unvaried mountain-top. All the ruggedness of the intervening hill-country was likewise effectively brought out. There seems to be a sort of illuminating quality in new snow, which it loses after being exposed for a day or two to the sun and atmosphere.
