are definitely determined, species selected, nursery sites located, dis- 

 posal of brush and dead timber considered, preliminary fire plans 

 made, and an estimate is given of the cost of the several operations. 



During the year the field investigations of forest replacement in 

 the Santa Barbara Forest Reserve, inaugurated and carried nearly 

 to completion in the fiscal year 1904, were finished, and the prelim- 

 inary office report was compiled in the form of locality and repro- 

 duction studies. 



The forest-replacement studies in the Sierra Forest Reserve were 

 completed in December, 1904. A full office report describes the types 

 of the Sierra forest, the extent to which natural reproduction may be 

 depended upon to reclaim chaparral and reforest denuded areas, 

 the areas on which planting is advisable, and the species suitable for 

 planting. 



An investigation of the advisability of forest planting for timber 

 supply and water conservation in the Salt Lake Forest Reserve was 

 made during the summer field season. One valuable result was the 

 beginning of hearty cooperation with the municipality of Salt Lake 

 in the interest of the city's water supply. The eastern part of the 

 Lewis and dark Forest Reserve was examined to determine whether 

 the condition of the watersheds, the state of settlement, and the 

 value of the water and timber supplied by this region are sufficient to 

 warrant the preparation of a reforestation plan. An examination 

 was also begun to determine the advisability of forest planting on 

 denuded slopes in the Gunnison Forest Reserve, in Colorado, in con- 

 nection with the Uncompahgre Valley irrigation project of the 

 Reclamation Service. 



STATE COOPERATIVE WORK. 



The forest investigations in cooperation with the State of Cali- 

 fornia which began in July, 1903, were finished. Studies were con- 

 ducted by the Office of Forest Extension on the chaparral, its growth, 

 extension, functions, and the means of controlling it, and on forest 

 fires. The latter resulted in completed reports on fire conditions in 

 the San Bernardino, San Gabriel, Santa Barbara, San Jacinto, and 

 Trabuco Canyon forest reserves, and in Monterey County, on the 

 western slope of the southern Sierras, and in the Lake Tahoe region. 

 In addition, a systematic plan of fire protection was made and put 

 into operation on a lumber tract in Butte County, and reports on 

 slash burning and general fire protection were prepared. Most 

 important of all, a State forest code, based on a thorough field study, 

 was submitted to the legislature, and was passed in somewhat 

 amended form. It provides for the protection and management of 

 forests within the State, and creates a State board of forestry and a 

 technical administrative force consisting of a State forester and two 

 assistants. A general report on fire conditions in California is in 

 preparation. 



EXPENDITURES. 



The expenditures of the Office of Forest Extension during the past 

 year amounted to $53,970.96, or 12^ per cent of the appropriation of 

 the Forest Service. Contributions amounting to $3,792 were received
