INTRODUCTION. 
Owing to the fact that the active field work of the office accords 
better with the calendar year than with the fiscal year, it has been 
| thought best to report herein the work of the Divisions of Construc- 
tion, Maintenance, and National Park and Forest Roads for the past 
_ 18 months, and in the future to have the reports cover the calendar 
years. This bulletin takes up the field work of the above three 
divisions where Department Bulletin No. 53 (Object Lesson and Ex- 
perimental Roads, and Bridge Construction, 1912-18) left off. These 
three divisions have been formed from the one division of engineer- 
ing since Bulletin 53 was issued, and the records of work divided 
accordingly. 
As mentioned in Bulletin No. 53, the Office of Public Roads and 
Rural Engineering 1s empowered by a provision of the agricultural 
act to expend a portion of its appropriation “ for investigations of the 
best methods of road making and the best kinds of road-making mate- 
rials, and for furnishing expert advice on road building and mainte- 
nance.”! In the interpretation of this clause the desire of the office 
has been to demonstrate in a practical way the need for good roads, 
-as well as the benefits derived from them, and at the same time to
