The last weeks of April and the first of May found most of the immigrants pulled out upon the road, in companies of fifties and hundreds. They were in the Indian country on the first day of travel, and not sure how such an invasion would be received by the savages, they were warned to keep compact, and in bodies large enough for protection. The Indians, men, women, and children, swarmed about every camp, and watched every movement. They were invariably treated kindly, and responded with kindness. The warriors sat upon their horses stolidly by the trails and watched the long wagon-trains, the herds of cattle, and especially the women and children, the like of which had never before invaded their domain. The weeks of travel across the grass-grown, flower-covered prairies of Kansas and Nebraska was a picnic occasion for the immigrants. It was well that it was so. They did not have many afterward. [Illustration: MARMADUKE ISLAND. (B. H. Gifford, photo.)] The wagons were soon strung out over a long line. Dr. Whitman did not start with the head of the company. In a letter to a friend he wrote, "I remained behind until the last wagon was on the road." There were many who needed advice as to proper outfit, what to take, and what to leave, many who needed encouragement to start at all. When all had moved he rode rapidly to the head of the column, to overtake it before it reached the Platte, the first wide river to be crossed. The Platte is not a dangerous river if forded properly, but it looks threatening to timid people. It is nearly one mile wide, and it is about breast deep in ordinary stages. It runs over a bed of sand, and the secret of safety is to keep on the sand bars and keep moving. A halt, even for a few minutes, allows the feet of animals, or the wagon wheels to sink into the sands, and they are not easily extricated. Upon reaching the bank of the river, horsemen upon the best horses survey the route by zigzagging up and down, finding the shallowest water upon the bars, which are constantly shifting. The train of wagons are arranged to follow each other, a dozen or more yards apart, with horsemen at each vehicle to give immediate assistance in case of break or accident. The first driver keeps his eye upon the careful guides, picking the shallowest route. Careless endeavors to pull straight across, instead of pulling two miles around to gain one, involved trouble. The murky water is surcharged with sand, which is forever blown into it as it winds through the great plains, and is the source of the Missouri River's excessive supply of sand. It proves to be pure water if allowed to stand and settle. A bucket of water standing over night in the morning will be clear, with an inch of pure sand on the bottom. If the old maxim is true, "A fellow needs sand in his craw," he easily gets it on the Platte. Our immigrant party, wisely directed, forded the river safely with all its stock. Care was taken in fording all rivers to place
