 The remainder of the roadbed to be graded to conform with the macadam. DOT ton, rolled and spripkled to form an earth road for summer use.
 The essential features of the work on that portion of said highway between the San Francisco County line and the Santa Cruz County line are to correct the ex- isting dangerous and al times impossible grades and judgments, and to grade a roadbed not less than twenty (20) feet in width upon grades not exceeding four (D per cent the roadbed on this portion of said highway to be not less than forty (40) feet in width in the level cuttings and twenty (20) feet of graded roadway on sidehill cuttings.

 Tn their auxiliary report the mem bers of the Highway Commission say:
 We have made special studies of the development of suitable quarries- In ex- amining all existing quarries and many available sites we are pleased to find that your county furnishes an abundance of excellent materials. There exist several localities from which an excellent sub grade or foundation layer of material can be obtained.
 From some of these the hardest hinty jasper tor chert can be separated which mixed with one-fourth of the siliceous limestone from near Byrnes store, will make a surface material of the best ouaI- ity. In regard to this latter material if has been alleged that it injures the var nish and paint of vehicles. We sub- mitted t..As stone to d preliminary exami- nation in the College of Chemistry in the University of California, and ind this idea entirely unfounded. the material being neutral and harmless: the opnosifa idea being probably advanced as an ex- cuse for neglect in promptly cleaning ve- hicles of dust or mud, which from any source is injurious if neglected
 The mixture of the hardest clean and Weli-crusted Jasper, with a proper pro- portion of the siliceous limestone as n cementing and binding material. with thorough rolling and sprinkling forms a good road surface of unexcelled quality and durability, and we are pleased fo nots that your county furnishes sucn excellent
