also the River Sum^ flowing N. W. into Lake Salisbury/ The 

 cold was very great ; but fortunately there was no rain^ and 

 only two men died from cold and exertion. The highest point 

 reached was (by boiling-point) 14,894 ft., and none of the 

 other peaks were more than 50 ft. higher. On descending 

 the south side of the mountain the first of the celebrated caves 

 was met with at a height of 7500 ft. 



'^On arriving again at Qua Sundu or Mumiyas,Mr. Jackson 

 and his friends were astonished to hear that the redoubtable 

 Dr. Peters had passed by a month before and had hoisted 

 his flag all over the country. Mr. Jackson pulled down 

 Dr. Peters^s flag and hoisted the Company's instead, and after 

 buying a supply of food, started for Uganda by the north side 

 of the lake — along the track of Bishop Hannington. The 

 most interesting experience of this part of his travels was 

 his acquaintance with the country of Wakoli, in Usoga. The 

 change is described as marvellous. They marched ' through 

 vast groves of bananas ' up to Wakoli's capital. Here they 

 were received with the most bounteous hospitality. 



'' On March 26 they left this land of friendship and 

 abundance, and on April 5 reached the Nile, which was 

 crossed on the following day, and Mwanga's capital, Mengo, 

 reached on the 14th. 



" On June 24 Mr. Jackson left Mumiyas (Qua Sundu) in 

 charge of a headman and party, and marched coastward by 

 way of Kabaras, Elgeyo, and Lake Baringo to the north end 

 of Lake Naivasha, whiqh was reached oji the 27th. On the 

 8th of August he arrived at Machakos after an absence of 

 eleven months. The party returned to Mombasa on Septem- 

 ber 3, after accomplishing the longest and most successful 

 tour of exploration yet made in those regions.'' 



The accompanying sketch of Mr. Jackson's route (p. 234) 

 has been taken, by permission, from the large map prepared 

 by the Royal Oeographical Society for the illustration of the 

 narrative of Mr. Jackson's journey, read before that Society, 

 February 9th, 1891 (see Proc. R. G. S. for this year).

 made during this journey, and commence with the Passeres
