But, if any persons obstinately object to the style and matters of my Narrative of Desert Travel, I shall likewise as obstinately endeavour to hold my ground. To all such I say,--"Go to now, ye objectors and gainsayers, and do better." My mission was _motu proprio_, and I plunged in The Desert without your permission. But I am but one of the two hundred millions of Europe. You can surely get volunteers. You have the money, the rank, the patronage, and the learned and philanthropic Societies of Europe at your back. Send others; inspire them yourselves, and they may produce something which you like better than what I have given you. If I am not orthodox enough,--if I have not reviled the Deism of The Desert sufficiently to your taste,--send those who will. A little less zeal in Exeter Hall, and a little more in The Desert, would do neither you nor the world any harm. A little less clamour about Church orthodoxy, or any other doxy[1], and a little more anxiety for the welfare of all mankind, would infinitely more become you, as Englishmen and Christians, and be more in harmony with that divine injunction, which sent out the first teachers of Christianity amongst the Greeks and Barbarians, in The City and The Desert, to preach the Gospel to every creature under heaven. If I be too much of an abolitionist, send one who admires slavery, and who will write up the Slave-Trade of The Desert. I have written in my way: you write in your way. If my pages disclose no discoveries in science, this I can only lament. When a man has no science in him, or no education in science, he can give you none. But what are your European Societies of Science for? Are they play-things, or are they serious affairs? Have you neither money nor zeal to equip a scientific expedition to The Desert? If not, I cannot help you. By the way, I was astonished to receive, since my return, a note from one of your eminent geologists, repudiating and protesting against all knowledge of the subject of "The Geology of The Desert." And The Desert is a fifth part of the African Continent! Yet this gentleman dogmatizes and theorizes on all geological formations, and can tell the whole history of the geology of our planet, from the first moment when it was bowled by the hand of The Omnipotent in the immensity of space, of suns and systems! If such presumption and self-willed ignorance discover themselves in great men, what are we to expect of little men? In the following pages, I have encroached upon my Reports, to describe several of the Oases of The Desert, besides giving as much of the routes as was necessary to render the Narrative of my journey intelligible. But this is all I could conscientiously do. For the rest of the geographical information, the public must wait.
