The scenes of horror and despair which transpired in the snowy Sierra in the winter of 1846-7, need no exaggeration, no embellishment. From all the works heretofore published, from over one thousand letters received from the survivors, from ample manuscript, and from personal interviews with the most important actors in the tragedy, the facts have been carefully compiled. Neither time, pains, nor expense have been spared in ferreting out the truth. New and fragmentary versions of the sad story have appeared almost every year since the unfortunate occurrence. To forever supplant these distorted and fabulous reports - which have usually been sensational new articles - the survivors have deemed it wise to contribute the truth. The truth is sufficiently terrible.
