The Adventure Of The Engineer'S Thumb
"'There is a drive, then?'
"'Yes, our little place is quite out in the country. It is a good seven miles from Eyford Station.'
"'Then we can hardly get there before midnight. I suppose there would be no chance of a train back. I should be compelled to stop the night.'
"'Yes, we could easily give you a shake-down.'
"'That is very awkward. Could I not come at some more convenient hour?'
"'We have judged it best that you should come late. It is to recompense you for any inconvenience that we are paying to you, a young and unknown man, a fee which would buy an opinion from the very heads of your profession. Still, of course, if you would like to draw out of the business, there is plenty of time to do so.'
"I thought of the fifty guineas, and of how very useful they would be to me. 'Not at all,' said I, 'I shall be very happy to accommodate myself to your wishes. I should like, however, to understand a little more clearly what it is that you wish me to do.'
"'Quite so. It is very natural that the pledge of secrecy which we have exacted from you should have aroused your curiosity. I have no wish to commit you to anything without your having it all laid before you. I suppose that we are absolutely safe from eavesdroppers?'
"'Entirely.'
"'Then the matter stands thus. You are probably aware that fuller's-earth is a valuable product, and that it is only found in one or two places in England?'
"'I have heard so.'
"'Some little time ago I bought a small place–a very small place–within ten miles of Reading. I was fortunate enough to discover that there was a deposit of fuller's-earth in one of my fields. On examining it, however, I found that this deposit was a comparatively small one, and that it formed a link between two very much larger ones upon the right and left–both of them, however, in the grounds of my neighbours. These good people were absolutely ignorant that their land contained that which was quite as valuable as a gold-mine. Naturally, it was to my interest to buy their land before they discovered its true value, but unfortunately I had no capital by which I could do this. I took a few of my friends into the secret, however, and they suggested that we should quietly and secretly work our own little deposit and that in this way we should earn the money which would enable us to buy the neighbouring fields. This we have now been doing for some time, and in order to help us in our operations we erected a hydraulic press. This press, as I have already explained, has got out of order, and we wish your advice upon the subject. We guard our secret very jealously, however, and if it once became known that we had hydraulic engineers coming to our little house, it would soon rouse inquiry, and then, if the facts came out, it would be good-bye to any chance of getting these fields and carrying out our plans. That is why I have made you promise me that you will not tell a human being that you are going to Eyford to-night. I hope that I make it all plain?'
