to the Federal Government, but to the States, by way of en- 

 couraging simplicity and standardization. Still further progress 

 was made by voluntary cooperation on the part of the State officials 

 through a conference of testing engineers, held at this office, on Feb- 

 ruary 12-17, 1917. This conference recommended to the States 

 standard forms of specifications for materials, standard methods of 

 testing materials, standard forms for reporting test results, and 

 standard methods of samjjling materials. A connnittee of the Ameri- 

 can Association of State Highway Officials, working in conjunction 

 with officials of this office, fornuilated standard specifications which 

 should prove most helpful to highway work in the various States. 



From the foregoing it is evident that, aside from the material 

 benefits involved in the appropriation of Federal funds to aid high- 

 way construction, there has alread}^ been brought about a vast amount 

 of benefit through improvement in organization and methods, and in 

 the correlation, systematizing, and standardizing of highway work. 



Considering the immense amount of preparatory legislation and the 

 working out of rules and regulations, bases of procedure, and the 

 establishment of the necessary organization, the fiscal year 1917 

 makes an impressive showing as to actual road construction under 

 the terms of the act. At the close of the fiscal year there had been 

 •received for consideration by the department 92 projects from 26 

 States, involving an aggregate length of 948.78 miles at an estimated 

 cost of $5,435,702, on which Federal aid was requested to the extent 

 of $2,433,934. Of these projects 23 had been approved at the close 

 of the fiscal year, involving a total length of 188.58 miles at a total 

 estimated cost of $1,845,433, for which Federal aid was requested to 

 the amount of $846,152. The projects as approved are shown in the 

 following table :
