7 o8 TRAVELS TO DISCOVER 



1 77 1, the quantity that fell in the fame circumference was 

 41.355 inches in the fame fpace *. 



In 1770, Auguft was the rainy month; in 1771 July. Both 

 thefe years the people paid the meery, and the Wafaa Ullah 

 was in Auguft. When July is the rainy month, the rains 

 generally ceafe for fome days in the beginning of Auguft, 

 and then a prodigious deal falls in the latter end of that 

 month and the firft week of September. In other years, July 

 and Auguft are the violent rainy months, whilft June is 

 fair. And laftly, in others, May, June, July, Auguft and the 

 firft .week of September. Now we mall fuppofe (which is 

 the moft common cafe of all) that every month from June 

 doubles its rain. The Wafaa Ullah generally takes place a- 

 bout the 9th of Auguft, the tribute being then due, and 

 all attention to the Mikeas is abandoned at 14 real peeks, 

 the Caliih is then cut, and the water let down to the Delta.. 



Now thefe 14 peeks are not a proof how much water 

 there is to overflow the land ; for fuppofing nine days for 

 its paffage from Ethiopia, then the 9th of Auguft receives 

 at Cairo no later rains than thofe that have fallen the ift 

 of Auguft in Ethiopia, and from that date till the 17th of 

 September, the Nile increafes one third of its whole inunda- 

 tion, which is never fufFered to appear on the Mikeas, but 

 is turned down to the lakes in the Delta, as I fuppofe it al- 

 ways has been ; fo that the quantity of water which falls 

 in Ethiopia hath never yet been afcertained, and never can 

 be by the Mikeas, nor can it ever be known what quantity 



of
