284 SUMMER. 



Those appearances are soon followed by a very 

 agreeable breeze along the shore, but it does not 

 reach to any great elevation in the atmosphere ; and 

 upon the summit of a hill two thousand feet in ele- 

 vation, it is barely felt, if felt at all ; and the only 

 change there, is a suspension of the land wind, and a 

 consequent increase of temperature, which, before mid- 

 day, sends the herds to their repose, and renders the 

 shelterless upland, notwithstanding its clear and bracing 

 air, almost insupportable. 



Still the summer day has its scenes of pleasure and 

 profit in the sultry hour ; for it is then that both man 

 and the animals find refreshment in the grove, by the 

 murmuring stream, or the sounding cascade. The 

 latter especially, as there a hot day has all the effect of 

 a shower upon the surrounding vegetation. The water, 

 if the fall has much altitude, falls in drops and pencils, 

 all sides of which come in contact with the air, which 

 evaporates a very considerable portion of their volume; 

 and even though the altitude be not so great as to 

 occasion a cloud of vapour which can fall vertically 

 upon the vegetation in a perpetual shower, the air 

 which descends and condenses over the falling water, 

 hurries towards the warmer surface around in a per- 

 ceptible breeze, blowing outward in all directions, and 

 refreshing the vegetation for a space proportioned to 

 the height of the fall and the quantity of water. A 

 wind may be always felt blowing out of the chasm or 

 cauldron into which a stream precipitates itself; but 

 though that wind be constant, it produces a very dif- 

 ferent appearance on vegetation from that produced by
