PRELIMIITARY EEMAEKS. 17 



The quantity of rain that fell, on an average of four years 

 in the author's time, was 44.88 inches ; the number of days in 

 a year in which there was heavy rain, 19 ; of showery rain or 

 drizzle, with fair intervals, 81 ; cloudy, 28 ; and of days per- 

 fectly fair and dry, 238. 



The mean temperature of Kotekgherby is about 3° higher 

 than that of Ootacamund ; that of Coonoor, and Jackatalla 

 probably six degrees warmer : less rain falls at any of 

 these places than at Ootacamund ; and it is generally dry at 

 each, when it rains at Ootacamund, from their being affected 

 by different monsoons. 



Ootacamund is 14| miles distant from Kotebgherry ; 

 from Coonoor 10 miles ; and from Jackatalla 9 miles. 



KoTEBGHERRY is about 12 miles from Coonoor ; and from 

 Jackatalla 10 miles. 



Coonoor is about 2 miles from Jackatalla, by the carr 

 riage road, and 1 mile by the bridle road. 



An important feature in every place resorted to by inva- 

 lids, is its accessibility ; we shall therefore state the distances 

 of the Neilgherries from the principal points on this side of 

 India ; and give a succinct account of the various Passes or 

 (jhats, leading to the table-land above ; and in a subsequent 

 Chapter we shall give Tables of the several routes, prefixing 

 directions for the guidance of travellers.

 cipal points in the Madras territory : 



1. From Madras, via Bangalore, 35? miles ; of which 71
