There is still great uncertainty about the Bonanza masses 
and the Rio Florido mass, while nothing very definite is 
known about the irons said to be in the vicinity of Presidio 
del Principe. The actual size and weight of the Ranchito 
mass in Sinaloa is still very uncertain. 
The discovery of the truth about these bodies will give 
ample scope to the energy of any enthusiastic and competent 
explorer and investigator, and the sooner the work is under¬ 
taken the better will be the chances of success.
