 from this source and replace it with stone or gravel. 

 The excavation for the road-bed need not be below the 

 stratum of gravel or hard-pan, though in the latter

case one line of tile should be put in at least three and 

 one-half feet deep, either in the middle or on one side 

 the upper side, if upon a side hill, as in Fig. 26. On 

 very wet land nearly level two lines of tile may be 

 needed, as shown in Fig. 27.

'Coarse gravel with the larger stones raked into the 

 bottom of the road-bed will make a good road if under- 

 drained. Broken stone if available will make a much 

 more permanent road than gravel, though it is very ex- 

 pensive and requires a heavy steam roller to compact 

 the different layers of stone. If neither of the above 

 materials comes within the means of the owner, a well- 

 rounded gravel road on top of the soil will serve a good 

 purpose in dry weather. When there is but little travel 

 over the road a well-compacted turf will be very satis- 

 factory. To make a turf road the land is back-furrowed 

 the desired width and the rounded surface made fine, 

 mellow, and rich. A liberal amount of lawn-grass mix- 

 ture is then sown and rolled in with a heavy roller.
