For a 1759 expedition it was recommended that wagon accessories include drag chains, grass cutting knives, axes, shovels, tar buckets (for lubricating axles), jacks, hobbles, and extra sets of such items as clouts (axle-bearing plates), nails, horseshoes, hames, linch pins, and hamestrings.[23] It is doubtful if many teamsters in the 1755 expedition had so complete a selection of equipment; campaign experience in the mountains of western Pennsylvania was necessary to convince them of this necessity. There is no evidence that the hame bells later to be found on professional teams were used at this early date. The advertisement[24] that was circulated for the 1759 expedition mentions a "slip bell ... for each horse" among the items necessary on an expedition, so it is possible that some drivers of the 1755 expedition may have used a single bell on each horse, as was the custom with pack horses. These bells, kept stuffed during the day, were unstuffed at night when the horses were put out to forage in the woods so that they might be more easily found in the morning. Orme mentions no bells, although he writes of other methods used to avoid losing horses at night. Early in May detachments of the Army began to arrive at Wills Creek. During the advance to Wills Creek the lack of transportation had been keenly felt. Wagons had been forced to shuttle back and forth between camps in order to keep all stores and provisions moving forward.[25] By the latter part of May the Pennsylvania wagons were coming in; about 90 arrived on May 20. That same night 30 wagons had to be sent on to Winchester to bring up to Wills Creek the provisions which could not be brought earlier for lack of wagons. Also, 300 of the pack horses had to be sent back to Conococheague, through which the wagons had just passed, to bring up the flour which agent Cresap of that place had through neglect or intention failed to forward in the wagons as he had been directed. On May 27, 100 wagons were on hand, with some still coming in.[26] According to the accounts of the commission later appointed to settle wagoner's claims, 146 wagons with teams, and about 510 pack horses were provided by Pennsylvanians to accompany the army.[27] [Illustration: Figure 7.--FARM-TYPE CONESTOGA WAGON, about 1850 in the collection of the author.
