The leading wagons follow him so nearly round the circle, that but a wagon length separates them. Each wagon follows in its track, the rear closing on the front until its tongue and ox-chains will perfectly reach from one to the other, and so accurate the measurement and perfect the practice, that the hindmost wagon of the train always precisely closes the gateway. As each wagon is brought into position, it is dropped from its team (the teams being inside the circle), the team unyoked, and the yokes and chains are used to connect the wagon strongly with that in its front. Within ten minutes from the time the leading wagon halted the barricade is formed, the teams unyoked and driven out to pasture. Every one is busy preparing fires of buffalo chips to cook the evening meal, pitching tents and otherwise preparing for the night. There are anxious watchers for the absent wagon, for there are many matrons who may be afflicted like its inmate before the journey is over, and they fear the strange and startling practice of this Oregon doctor will be dangerous. But as the sun goes down, the absent wagon rolls into camp, the bright, speaking face and cheery look of the doctor, who rides in advance, declare without words that all is well, and that both mother and child are comfortable. I would fain now and here pay a passing tribute to that noble and devoted man, Dr. Whitman. I will obtrude no other name upon the reader, nor would I his, were he of our party or even living, but his stay with us was transient, though the good he did was permanent, and he has long since died at his post. From the time he joined us on the Platte, until he left us at Fort Hall, his great experience and indomitable energy was of priceless value to the migrating column. His constant advice, which we knew was based upon a knowledge of the road before us, was "travel, travel, travel--nothing else will take you to the end of your journey; nothing is wise that does not help you along; nothing is good for you that causes a moment's delay." His great authority as a physician and complete success in the case above referred to, saved us many prolonged and perhaps ruinous delays from similar causes, and it is no disparagement to others to say that to no other individual are the immigrants of 1843 so much indebted for the successful conclusion of their journey, as to Dr. Marcus Whitman. All able to bear arms in the party had been formed into three companies, and each of these into four watches; every third night it is the duty of one of these companies to keep watch and ward over the camp, and it is so arranged that each watch takes its turn of guard duty through the different watches of the night. Those forming the first watch to-night, will be second on duty, then third and fourth, which brings them all through the watches of the night. They begin at eight o'clock p. m. and end at four o'clock a. m. [Illustration: REV. CUSHING EELLS, D.D. Founder of Whitman College.]
