water right, is leased from the Mount Wilson Toll Road Company. A 

 reservoir with a capacity of 23,000 gallons is situated 250 feet above 

 and 1,700 feet distant from the nursery. The company furnishes with 

 the land a cottage of four rooms and a stable. 



The site of the nursery was cleared, grubbed, plowed, cleaned of 

 roots and rocks, and fenced with rabbit-proof wire netting. A seed- 

 bed 48 bv 160 feet was prepared. It is now covered by a stationary 

 lath shade, 6 feet above ground, made to permit half sunlight, the 

 cost of which was |21!». 80. 



The area within the frame was seeded in the latter part of March 

 to bigcone spruce, (Coulter pine, knobcone pine, incense cedar, sugar 

 pine, Jeffrey pine, gray pine, deodar, pinon, and Monterev pine. A 

 small quantity of each of these species, together with some of the 

 largest species of chaparral, was also planted in open ground, to deter- 

 mine their ability to stand direct sunshine in germination. 



Thirty thousand trees have been transplanted from the seedbed in 

 Pasadena to the nursery at Henninger's Flats, with a loss not exceeding 

 3 per cent. 



PIKES PEAK RESEEVE. 



The study of forest replacement on the Pikes Peak Reserve, described 

 elsewhere, has prepared the way for the establishment of small nur- 

 series and the beginning of experimental planting on that reserve. A 

 report which is now in preparation describes in detail areas on which 

 planting is recommended, discusses the trees which should be used, 

 and locates available nursery sites. The beginning of planting forms 

 the subject of a recommendation for next year's work. 



SEED COLLECTING. 



The seed used on the reserves has all been collected by the Bureau. 

 An abundant crop in the case of several species which the Bureau is 

 planting extensiveh^, and in which seed production is irregular, made 

 it desirable to collect in quantities beyond the needs of the current 

 year. A total of 5,350 pounds of seed was collected in California, 

 Colorado, Michigan, Minnesota, and New Mexico, of western yellow 

 and Jeprey pine, goldencup oak, simpleleaf sumach, bigcone spruce, 

 jack pine, knobcone pine, hollyleaf cherry, red fir, white fir, and 

 sugar pine. 



FoEEST Replacement. 



Studies of the action of the forest in reoccupying ground which had 

 been denuded of trees have been carried on in Colorado, Kansas, New 

 Mexico, and southern New England. 



An examination of the problem of reforestation on the Pikes Peak 

 Reserve, Colo., was conducted on the watershed which supplies Col- 

 orado Springs, in the southern part of the reser\'e. Attention was 

 mainly given to the history of fires which denuded the mountains, the 

 distribution of young growth which has succeeded fires, the productive 

 power and rate of growth of the principal trees, the conditions which 

 influence forest replacement on the burned areas at high altitudes, and 

 the necessity of supplementing natural reproduction by planting. 



The study shows that the most serious fires took place at least fifty 

 years ago, and that some of the burns have been fairly stocked with
