THE ROOK. 135

 insects destroyed by rooks, we have only to refer to 

 a most valuable and interesting Paper on the Services 

 of the Rook, signed T. G. Clitheroe, Lancashire, 

 which is given in the Mag. of Nat. Hist., vol. vi.

 the killed dozen of the plunderers. This tempting 

 boon soon caused the country to be thinned of 

 grakles, and then myriads of insects appeared, to put 

 the good people in mind of the former plagues of 

 Egypt. They damaged the grass to such a fearful 

 extent, that, in 1749, the rash colonists were obliged 

 to procure hay from Pennsylvania, and even from

 from India to Bourbon, in order to exterminate the 

 grasshoppers. The colonists, seeing these birds busy 

 in the new-sown fields, fancied that they were search-

 poor grakles were proscribed by Government, and 

 in two hours after the sentence was passed, not a 

 grakle remained in the island. The grasshoppers 

 again got the ascendency, and then the deluded 

 islanders began to mourn for the loss of their grakles. 

 The governor procured four of these birds from 

 India, about eight years after their proscription, and
