At that period the white population consisted of merely about thirty thousand all told. The native community almost trebled the Dutch. Mr. Bryce, in his "Impressions on South Africa," describes the then state of the affairs of the Republic as anything but satisfactory: "There were hundreds of thousands of natives, a few of whom were living as servants under a system of enforced labour which was sometimes hardly distinguishable from slavery, while the vast majority were ruled by their own chiefs, some as tributaries of the Republic, some practically independent of it. With the latter wars were frequently raging--wars in which shocking cruelties were perpetrated on both sides, the Kaffirs massacring the white families whom they surprised, the Boer commandos taking a savage vengeance upon the tribes when they captured a kraal or mountain stronghold. It was the sight of these wars which drove Dr. Livingstone to begin his famous explorations to the north. The farmers were too few to reduce the natives to submission, though always able to defeat them in the field, and, while they relished an expedition, they had an invincible dislike to any protracted operations which cost money. Taxes they would not pay. They lived in a sort of rude plenty among their sheep and cattle, but they had hardly any coined money, conducting their transactions by barter, and they were too rude to value the benefits which government secures to a civilised people."
Among other things an attempt was made on the part of the Boers to annex the Orange Free State. President Pretorius crossed the Vaal in 1857, at the head of a large commando, with the intention of seizing on the neighbouring territory. He was doomed to disappointment, however, for his intended raid was stopped by the timely resistance of the forewarned President of the Orange Free State. An encounter was happily avoided through the intervention of Mr. Kruger, and finally the two Republics decided to mutually recognise each other's independent States.
But the ambitions of Pretorius merely smouldered. He still kept a greedy eye on the Orange Free State, and machinated for the union of the two States into a gigantic whole. He therefore refused the Presidency of the Transvaal for that of the Free State, in the hope of gathering into his own hands the reins of both governments. He was again disappointed, however, and in 1864 he returned and was re-elected President of the Transvaal.
