Mem.--If meat and bread, and the like, have to be carried, a very large
addition of weight must be made to this list, for the weight of a daily
ration varies from 3 lbs., or even 4 lbs., to 2 lbs., according to the
concentration of nutriment in the food that is used. Slaughter animals
carry themselves; but the cattle-watchers swell the list of those who
have to be fed.

expedition across a wild and unknown country, we may estimate as
follows:--
Beasts of burthen:--
An ass will not usually care more than about (net weight) 65 lbs.
A small mule 90
A horse 100
An ox of an average greed 120
A camel (which rarely can be used by an explorer) 300
It is very inconvenient to take more than six pack-animals in a caravan
that has to pass over broken country, for so much time is lost by the
