niences. Let him satisfy himself that he can live upon the fare of the 

 country, black beans, farhino, and carre secca or jerked beef, with 

 occasionally, as a treat, bacon or an old hen ; then he will require 

 only time, patience and money to make his expedition both profitable 

 and delightful. 



Assuming that the two former are not wanting, I will notice the 

 third. I suppose that two entomologists are fellow-travellers. They 

 will require six mules ; two saddle mules for themselves ; one for 

 their black, who attends to the mules;* and three cargo mules, one 

 carrying a couple of trunks for linen, &c, the two others entomologi- 

 cal, boxes and stores. These mules must be bought, at prices ranging, 

 according to the locality and demand, from 150 to 300 milreis. I say 

 they must be bought ; for if hired (as they may be) the amount of hire 

 for a journey of three weeks will exceed the amount of purchase-

 however long, supposing that they have been tolerably cared for, at 

 least two-thirds of the sums that were originally paid for therm 



With the mules must be bought, also, bridles, saddles and knee- 

 boots (if not brought out from England), and pack-saddles, hide- 

 coverings and halters for the cargo mules. The outlay account then 

 will stand as follows : —

making a total of 1380 milreis, or about £150. Of this at least £100 

 will be repaid at the end of the journey by the sale of the animals, 

 leaving £50 as the amount of the purchase account. The daily 

 expenses will be on the average
