These works were all completed between Mombasa and Teita by the end of September, and in all the other sections fourteen days later. The workmen, however, were not discharged, as a part of them were required for guarding and maintaining the road and buildings, and another part found occupation in the transport service on the newly made highway. The cost of construction for the whole by no means small undertaking was 14,500£, half of which went in wages and half in rations; the material used in the work cost nothing. By this time Johnston had completed the purchase of the draught-beasts required for the transport service, and had organised the commissariat of the caravans. His Masai friends procured for him in a few weeks the originally ordered 5,000 head of cattle; and as every despatch from the committee of the Free Society reported a larger and larger number of members on their way to the settlement, our order was increased to 9,000, exclusive of the 750 head of cattle, the unused remnant of our presents which we had left behind us in Useri and Masailand. As the committee had reason to anticipate that by the end of October the number of members intending at once to join the colony would reach 20,000, they had enlarged their orders for waggons to 1,000, and announced that fact to us in the course of September. Therefore, as every waggon--which weighed 14 cwt., and would carry ten persons, with 20 cwt. of luggage--would require four yoke of oxen, the total number of draught-oxen needed would be 8,000, in addition to a reserve of 200 head, and 1,550 oxen and cows for slaughter. Johnston received this message on the southern frontier of Masailand, and, as there was not time to return, he had to complete his provisioning in the districts of Kilima and Teita. Nevertheless he succeeded in collecting the full number of cattle and distributing them along the sixty-five stages between Mombasa and the Kenia without materially raising prices by his purchases in these favoured districts. He bought 8,500 oxen and 500 cows, and the cost--including the travelling expenses and wages of the buyers and drivers--amounted to no more than 8,650£--that is, the goods which we bartered for them had cost us this amount. Each head of cattle cost on the average a little over eight shillings, half of which represented incidental expenses, the bare selling price being less than four shillings a head.
