Excerpt: ...was nothing in it larger than a quarter of an inch. 1--; Sand Made Fine Road. The next spring I went up there again and found that stretch of road was (and still is, after 3 years) one of the finest stretches of road in the state. Our speed limit of 30 miles per hour is not sufiicient for that road. I consider that is one of our most valuable discoveries; that a light application of 2 or 3 inches of sand on clay will produce a road which is wonderfully satisfactory to travel over a good many months in the year. Now, I do not claim it will hold up a 12 or 15 ton motor truck in the spring. That kind oi road is not designed to do that. In It cost us some cases these roads become impassable if used by trucks, but they can be whipped back into shape as soon as the weather permits them to dry out. If you have not tried this you should do so. Put the road down 18 or 20 feet wide and make it 3 inches thick in the center, going out to a feather edge, and put the planer or road machine on it for a few days or a few weeks until the-trave1_comsolidlates it, and I will guarantee that you will be astonished at the result. The water bound stone macadam road has given us an infinite amount of trouble. We built many hundreds of miles of it 9 feet wide and as soon as the automobile travel came, it unravelled these roads and they went all to pieces. We then started to treat the surface with tars and asphalts, and after one or two treatments, we found that these narrow surfaces got very rough. At the present time the roughest roads we have in Wisconsin are our water bound macadam surface treated roads, and we have practically given them up. We are now scarifying these old 9 foot macadams down a good depth, spreading them out to 15 or 16 feet and putting on...
