130 LOCUST. 



the Philosophical Transactions we find that in the 

 year 1693 some swarms of this species of Locust 

 settled in some parks of Wales. Two vast flights 

 were observed in the air not far from the town of 

 Dol-galken in Merionethshire: the others fell in 

 Pembrokeshire. From a letter published in the 

 38th volume of the same work it appears that some 

 parts of Germany, particularly in the March of 

 Brandenburgh, &c. suffered considerable injury 

 from the depredations of these animals. They 

 made their appearance in the spring of the year 

 1732, from flights which had deposited their eggs 

 in the ground the preceding year. They attacked 

 and devoured the young spike of the wheat, &c. and 

 this chiefly by night, and thus laid waste many 

 acres at a time beyond all hope of recovery. In 

 the 46th volume of the same Transactions we find 

 a description of the ravages of these animals in 

 Walachia, Moldavia, Transylvania, Hungary, and 

 Poland in the years 1747 and 1748. 



" The first swarms entered into Transylvania 

 in August 1747: these were succeeded by others, 

 which were so surprisingly numerous, that when 

 they reached the Red Tower, they were full four 

 hours in their passage over that place; and they 

 flew so close that they made a sort of noise in the 

 air by the beating of their wings against one an- 

 other. The width of the swarm was some hundreds 

 of fathoms, and its height or density may be easily 

 imagined to be more considerable, inasmuch as 

 they hid the sun, and darkened the sky, even to 

 that degree,. when they flew low, that people could
