Nauroz (the new-year's day), but within the first ten days of the year ; 

 but if about is not added, it means exactly the day mentioned ; for example, 

 it sets in on the tenth day of the year, means that it sets regularly in on 

 the tenth. At the time when the ancient Arabic pilots wrote their works, 

 the radical Jalalian year was not yet established, neither were the Roman 

 months known in these countries, and they calculated, therefore, according 

 to the Yazdajirdian year ; but the calculation of the Jalalian year is much 

 easier. Be it known, that at the time when the above-said book (the Co- 

 lumn of Sl'I.eima'n Ben Ahmad) was translated, the Nauroze Sultdni, that 

 is to say, the Jalalian new-year's day, fell on the 135th day of the Yazdajirdian 

 year, that is to say, on the 15th of Mordad*. 



The monsoons are of two sorts, the western ones, called by the seamen Rihi 

 Kewsf, the second, the eastern ones called RxhiAzib%, and Sabd§. The eastern 

 monsoons sub-divide again in two classes ; 'during the first, the Indian seas 

 are shut ; nevertheless, they are called Mausim\\ (season). 

 Section 3. The first sub-division of the first sort called Rdser-rih* ; 

 (headwind), or the monsoon of the olives, (Mausimi zaitani.) 



The monsoon of Aden, Gujerat, and Concona, from the 130th day of the 

 Yazdajirdian year, which is the 360th of the Jalalian, that is, five 

 days before the next new-year's day (16th March). The point from 

 which it arises is Aden; sometimes it ceases within the 170th of the 

 Yazdajirian year, which is the 35th Jal. (24th April). From Aden ships set 

 out within the 150th or 160th day of the Yazdajirdian year, which answer 

 to the 15th or 25th Jal. (4-1 4th April), they arrive on the 180th of the 

 Yazdajirdian, or 45th of the Jalalian year (4th May), at Sheher ; proceed 

 from thence to Gujurat and Concona, but not onwards to Manibarff 

 (Malabar), where there is much rain and danger. 



2. The monsoon of Sheher, Gujerat, Malabar and Concan. The high- 

 est monsoon of Gujerat sets in within the 150th of the Yazdajirdian, or 18th 

 of the Jalalian year (7th April). The highest monsoon of Concan sets 

 in within the 140th Yazdajirdian or 5th Jalalian (25th March). The 

 monsoon of Malabar within the 130th Yazdajirdian or 360th Jalalian (16th 

 March), five days before the beginning of next year++. 



3. The monsoon of Dhofdr, Gujerat, and Malabar, sets in within the 

 100th Yazdajirdian = 330th Jalalian (14th February) : when the navi- 

 gation is open to all India, for Dlwfdr is the place from whence the Ri- 

 hi Kews (the western monsoon) sets forth, which blows within the 70th 

 day of the Yazd. year, equal to the 300th of the Jalalian (15th Jan.) 



* The Yazdajirdian Nauroz falling in the year 1553, on the 28th October, th e 

 Jal&lian, on the 135th day, answeredto the 12th of March, 1554 ; this is, however, 

 not the true equinox, which in the year 1554 fell on the 11th, on which day the 

 longitude of the sun was = 0.

XX Here the calculation does not answer, as the number of the one or the other 

 must be changed if the difference of 135 should be made out: this is also the case 

 ■with the two following ones.
