Geologists, working in cooperation with highway engineers, have been of great assistance to them, and of great economic service to the public in searching out sources of material, in classifying and identifying rock formations, and in passing judgment upon the suitability of different rocks for use in highway projects. More recently geologists have rendered great assistance in the study of slides in earth embankments in both the cut and fill sections. All of these and innumerable other associations have developed the mutual respect and spirit of cooperation now existing between geologists and highway engineers. This seems particularly fitting since the rocks and soils studied by the geologist are so closely associated with the works of the highway engineer which are constructed of these materials, and finished in contact with members of the same materials.
