But conscience, in Walter's breast, was too faithful a watchman to be easily silenced. If the Christian had found the pillar of fire his cheering light in the dark hours of tribulation, the pillar of cloud was now shading him from the more dangerous glare of prosperity's sun. It was not only that it kept his life pure in the midst of many temptations, but it made him search his own heart. Walter became painfully aware that, while advancing in everything else, he was not advancing in spiritual life. Secular study sometimes encroached on time that would otherwise have been given to study of Scripture; and the image of Flora's dark eyes intruded often on his devotions. Walter was not contented with his own state, and that uneasiness was in itself a good sign.
Was Walter's promise to Sultána forgotten amidst the eager pursuit of knowledge and the fascinations of civilised life? No; morn and even the little band of Christians in the Eagle's Nest were remembered in earnest prayer. But it is natural that visible surroundings and the interests of daily life should engage more constant attention than what belongs to memory alone. During the fascinating two years which Walter passed at college, he received no communication of any kind from his friends in the fort. Walter wrote repeatedly to Ali Khan in a large printed hand, which he had taught Sultána to read, but it need hardly be said that there was no available post to the mountain home. Walter was in uncertainty as to whether his letters or presents ever arrived, as no one in the fort was able to write. This difficulty of communication, with doubt as to its success, was very discouraging to Walter. It seemed as if he were as little able to exchange tidings with his Afghan friends as if they existed only in dreamland.
And, as time wore on, increasingly did Walter's engagement to return to his little flock in the mountains press on his heart like a chain. Every one with whom the young man entered on the subject, more or less condemned his plan as impracticable and wild. Yet Walter could not let himself be persuaded that a resolution made with earnest prayer should be put aside because man thought it unwise. The remembrance of the blessing which had followed his efforts in the Eagle's Nest could not be blotted out by college professors speaking of wasting talents, which would give him influence over thousands of educated minds, on a few bloodthirsty Afghans. Walter was not convinced when Sir Cæsar spoke indignantly of a promising, rising young man throwing himself utterly away; but, though unconvinced, Walter felt that inclination was constantly drawing him more and more away from a course pointed out by honour and duty, till he regarded almost with aversion the idea of returning to Afghanistan.
"I must end this miserable indecision," thought Walter, "and act as my conscience prompts."
Young Gurney wrote a letter to the committee of a Missionary Society in England, describing his own position. He informed the committee that a bishop in India had consented to ordain him, after a two years' course of study, should he pass the required examination. The examination would be over before a reply could be received from England, and should the result be favourable, Walter offered himself to the Society for a post in Afghanistan. He described the small nucleus of a Christian Church existing in the Eagle's Nest; it might be a centre of missionary effort amongst a people yet unreached by the Gospel. Walter mentioned no personal qualifications but fluency in Pushtoo, and an earnest desire to win souls.
Walter despatched his letter to England, and then confessed to Miss Dashley what he had done. Flora looked surprised, and a little annoyed, but presently said with a smile, "The committee will not accept you; you will have to submit to remain with us, Walter." It was the first time that the young lady had called him by his Christian name; how exquisitely sweet it was to hear that name from her lips!
"Would you believe it, papa?" said Flora to her father, who entered the room at that moment; "Mr. Gurney is offering himself for a mission in Afghanistan."
"The thing is impracticable," said Sir Cæsar in the tone of one who lays down the law. "My term of service being nearly completed, in two months we shall start for England, and Walter had better come with us. You will have your uncle's interest to give you a good start in life," he continued, addressing himself to young Gurney; "I advise your entering on a course at the bar. I should not wonder," he added more gaily, "if you ended your career on the woolsack."
As in the interim between sending his letter, and receiving its reply, Walter never entered again with Flora on a distasteful subject, the lady almost forgot the whole affair. She was much engaged in preparations for a fancy ball, which she could not persuade the student to attend even by the lure of seeing her in Afghan costume personate his favourite Sultána. But often—very often—even in the midst of hard study, did Walter think, almost without fear, of what the mail from England might bring. His reading up for examination gave him a fair and true excuse for seeing less of Miss Dashley; but very hard was it to keep almost entirely away, except on Sundays, especially as the dreaded time of parting was every day drawing near and more near.
With almost feverish impatience the secretary's reply was opened when it arrived about a week after Walter had passed his examination with brilliant success. The letter, though couched in rather formal terms, was full of Christian courtesy. The committee, it said, had given due consideration to Mr. Gurney's offer to devote himself to founding a mission in the country of the Afghans. His high motives, his devotion and zeal, were highly appreciated. But after much thought the committee felt unable to send any agent into so dangerous a field, beyond the protection of the British flag. If Mr. Gurney would volunteer for work in India, his offer would be gladly entertained.
