For is there aught in sleep "Can charm the wise ? To lie in dead oblivion, losing half The fleeting moments of too short a life ; Total extinction of th' enlighten'd soul ! Or else to feverish vanity alive, Wilderd, and tossing through distemper'd dreams?

Էջ 153 - ... a free circulation of air. If you rear a piece of timber, newly cut down, in an upright position in the open air, it will last for ages. Put another piece of the same tree into a ship, or into a house, where there is no access to the fresh air, and ere long it will be decomposed. But, should you have painted the piece of wood which you placed in an upright position, it will not last long ; because, the paint having stopped up its pores, the incarcerated juices have become vitiated, and have caused...

They say he is a benefactor who makes two blades of grass grow in the place of one ; and I am sure he is equally a benefactor who converts a waste into a garden, instead of a garden into a waste. If even you look at it from a utilitarian point of view, it is still the same ; since beauty means health, and sweetness, and enjoyment; what the...
