Frost
Frost, like snow, is the result of sublimation of water vapor in saturated air. If solid surfaces in contact with the air are chilled below the sublimation point, then spicules of ice grow out from the solid surface. The size of the crystals is a matter of time and the amount of water vapor available.Frost is often observed around cracks in wooden sidewalks due to the moist air escaping from the ground below. Other objects which frost develops on are those with low specific heat and high thermal emissivity[?], such as blackened metals; hence the accumulation of frost on the heads of rusty nails. The apparently erratic occurrence of frost in adjacent localities is due partly to differences of altitude, the lower areas becoming colder. It is also affected by differences in absorbtivity and specific heat of the ground which in the absence of wind greatly influences the temperature attained by the superincumbent air. It should be understood that vegetation isn't damaged by frost itself, but by cold air; the appearance of frost merely indicates that the temperature has dropped below the freezing point. The formation of white frost on the indoor surface of window panes indicates low relative humidity of the indoor air, otherwise water would first condense in small drops and then freeze into clear ice.

WHEN that eye.html">eye of light.html">light.html">light shall in darkness fall,
When the bloom of that rich red lip shall fade,
Are the holy vows I have breathed to you;
And in the blue heavens I'll seek my bride.
Then we'll tell, as we tread yon azure sphere,
And our spirits shall joy that, their pilgrimage o'er,
Its last faint beam hath fled,
In ocean's wavy bed.
Thy waves, Indifference, roll;
That death-pool of the soul.html">soul.
Spreads o'er the heavens the shadowy night
So human pleasures, frail and light,
So fades the sunshine of the breast,
So friendship's fervours sink to rest,
From dewy evening's purest sky,
Dear Eva, from thy moonlight eye.
I looked around the summer grove,
For all had felt that look of love
As fair, as false thy glances fall;
That sheds its light alike on all.
TO A LADY WITH A WITHERED VIOLET.
THOUGH fate upon this faded flower
Its odour'd breath defies his power,
No longer wildly thrill,
Its soul is with me still.

I SAT me down upon a green bank-side,
Whose waters seemed unwillingly to glide,
