During the spring and summer a large number of the people find employment in the regions near the poles, especially those whose work is connected with the canal system and who have to see that the water from the melting snow-caps is turned into the proper channels and everything connected therewith kept in good working condition. All these workers, however, migrate to warmer latitudes as the very long and dreary winter approaches. * * * * * I have just received some interesting and very unexpected news which, as some writer says, "gives me furiously to think." John and M'Allister came to me asking anxiously whether I had fixed the date for our departure. I replied that we should probably keep to our original programme and leave about the beginning of December, but asked John why he was so anxious to know? "Well, Professor," he answered, "there is more than one reason for my question. I do not think our stay should be prolonged. Haven't you noticed any change in us?" I replied that "I had not seen any particular change or alteration in them, except that in build and general appearance they were becoming more like the Martians." "Yes, Professor," exclaimed John, "that's just it. I don't know whether it is the Martian air or the Martian food, or the combination of both, but we certainly are becoming more like Martians every day. Our eyes are becoming luminous, our complexions and features are changing, and, by Jove! if I haven't grown nearly two inches since we came here! If I go on like this I shall soon be such a giant that I shall not care to go back at all." "Really, John," I said, "is it so bad as that? Now I come to look at you critically you certainly do look taller; and I can see a little luminosity in M'Allister's eyes, and rather more in yours. I suppose, being the youngest, you are more susceptible than M'Allister or myself." "Yes, I think that must be the case, Professor," remarked John. "However," I added, looking at him and smiling, "you told me there were more reasons than one, so I suppose you have kept the weightiest reason to the last." "Well, I don't know about its being the weightiest reason," he answered, "but we shall require nearly four months to accomplish our journey to England after we leave here, and I reckon that by that time my stock of tobacco will be pretty nearly used up. I have given a lot away to our Martian friends, and I've tried some of the native growth; it's rather decent stuff, but not a patch upon my mixture." I burst out laughing in such a hearty fashion that it set them off too, as I remarked, "Ah, John, I had a shrewd idea that there was something more behind your anxiety than the fact that you were becoming Martianised." "Heh, John," exclaimed M'Allister, touching him playfully on the shoulder, "the Professor had you all right that time, I'm thinking!" John blushed up to the eyes, and said no more.
