stitution of the name water-resources branch for hydrographic 

 branch. 



The technologic branch includes the division of fuels and the 

 division of structural materials. These changes merely organize 

 into a recognized branch of the Survey, the work which has 

 been carried on for several years past in investigating the prop- 

 erties of the structural materials, the chemical composition and 

 adaptabilities of the fuels, present waste, and methods for pre- 

 venting smoke and waste. 



The changes in the topographic branch have been to create 

 five divisions instead of two and the appointment of three of the 

 most experienced topographers as inspectors of topographic 

 work. The publication branch has also been reorganized to some 

 extent and desirable changes instituted in the business methods 

 of the Survey. 



The changes noted are a continuation of the progress instituted 

 years ago by Walcott, by which better, organization has kept 

 pace with the great growth of the Survey, tending to promote 

 efficient and uniformly high-grade work. The Survey has also 

 appreciated the needs of the public in obtaining information con- 

 cerning the national resources and how best to use and conserve 

 them. With strange shortsightedness, however, Congress 

 reduced the appropriation of the water-resources branch by 

 25 per cent, making it necessary to break the continuity of many 

 stream measurements. 



The plan of operations for the year involved an expenditure 

 of $1,758,620; this amount is practically the same as for the 

 previous year, $213,700 of it being allotted to geology. Of this, 

 25 per cent was devoted to areal and stratigraphic geology, 39 

 per cent to economic geology, 25 per cent to investigations in 

 paleontologic, stratigraphic, glacial, and physiographic geology, 

 and 11 per cent to supervision and administration; $14,000 was 

 also allotted to paleontology. The disbursements for topographic 

 surveys during the past year were $327,400, and the new areas 

 surveyed in 1906-7 amounted to 32,448 sq. miles. The total 

 area surveyed in the United States up to the present time is 

 1,025,065 square miles, or about 33 per cent. J. b.
