"Sir: We, the undersigned citizens of the Territory of New Mexico, have been acquainted with Mr. Christopher Carson for a number of years, indeed almost from the time of his first arrival in the country. We have been his companions both in the mountains and as a private citizen. We are also acquainted with the fact that for the past few months, during his leisure hours, he has been engaged dictating his life. This is, to our certain knowledge, the only authentic biography of himself and his travels that has ever been written. We heartily recommend this book to the reading community for perusal, as it presents a life out of the usual routine of business, and is checkered with adventures which have tried this bold and daring man. We are cognizant of most of the details of the book, and vouch for their accuracy."
