Photographs taken of theland will show the nature of the soil,farms and all their details, roads,bridges, systems of drainage, telegraphand telephone lines, power lines, gaslines, forests, and scrub land, and willreveal plainly the value of each farmphotographed and the results of thefarmers labor.
