This being the cafe, one mayexpe£i to arrive at the knowledge of what is at lead intendedfor a proper days journey for a camel, under the circumftancesof the cafe : and indeed the refult is fuch as to prove what Ihave before advanced, refpefting the length of the mean journiesof both kinds. For having fele£led from the five above-mentioned journals, the length of the apparently optionaljourniesin each ; it appears, that the heavy caravans went yh. 51 a mean of 24 fuch days : and the light caravans 9 h. 8 m,on a mean of 38 days. In both of which cafes, as mighthave been expected, the length of the mean optional day, isfomewhat longer than that of the whole journey; in whichthere is a wider field for delays and accidents. The compa-nion is as follows: Heavy caravan. I Mean daily rate of thewhole journey . lOf optional days- . Diftance in Britifnmiles. Light caravan. Diflance in Thus *13 Travellings as performed by Camels. 14 Thus the mean daily rate of the heavy caravan, appears to he18,64 Britifh miles, reckoning two miles and an half for eachhour 1 and 19,06 if taken at 2*56 : and the mean rate of thelight caravan 22,17 miles, at 2J ; 32,7 at 2,56. In order to apply this fcale with effedt, to the African geo-graphy, it is neceflary to ftate the number of days that thecaravans ufually halt on the road ; for as yet I have only con fi-ltered their rate of motion : but it is evident, that if the lengthof the journey in the grofs, is given, the requifite informationwill not be obtained, without a previous knowledge of the timeloft by neceflary, or unavoidable halts on the road. My enquirieshave furnifhed me with an account of 13 halts, to 149 days oftravelling; or, which is the fame thing, 13 halts out of 162days,
