FORESTRY AND IRRIGATION 



May 



Sacramento valleys, full use has been 

 made during recent years of subsur- 

 face waters, and millions of dollars 

 have been invested in their develop- 

 ment and utilization. 



Survey Work Messrs. E. M. Douglas

01 the topographers of 



the United States Geological Survey, 



are now in Porto Rico engaged in 



running the boundary line of the Lu- 



quillo National Forest. The total 



length of the line to be run is about 



forty miles, and it is expected that the 



work will consume about a month's 



time. As stated in the last number of 



this magazine, the forest covers nearly 



66,000 acres (about 100 square miles) 



in the northeastern part of Porto 



Rico, and is the only national forest 



in the insular possessions of the 



United States. 



Change in The President has 



Boundaries of just signed a proc- 

 Nationai lamation c o m b i n ing 



the Manzano and Mt. 

 Taylor National Forests, New 

 Mexico, under the name of the Man- 

 zano National Forest. Besides desig- 

 nating the two forests as Manzano No. 

 I and Manzano No. 2, the proclama- 

 tion makes several changes in the 

 boundaries of each. Approximately 

 70.636 acres have been added to the 

 old Manzano and an elimination of 

 that part of the forest lying south of 

 the Belen cut-off of the Santa Fe Rail- 

 road, amounting to 167,156 acres, has 

 been made. 



The additions are located along the 

 northeast portion of Manzano No. i, 

 bordering the Estancia Talley. This 

 includes the greater portion of the 

 north and south San Pedro Moun- 

 tains. This addition lies between the 

 San Pedro Grant, Tejon Grant, and 

 Ortiz Mine Grant. INIuch of the ex- 

 treme" : northern portion of the ad- 

 dition covers the steep slopes of the 

 North and South San Pedro Aloun- 

 tains, wdiile the southern part covers a 

 more or less smooth country along the 

 east s^ope of the Manzano Mountains. 



Considerable yellow pine is found 

 in the area included in this recent " 

 proclamation in the vicinity of the San 

 Pedro Mountains. On North San 

 Pedro Mountains there are scattered 

 clumps of yellow pine and red fir,, 

 while on the south side of the moun- 

 tains there is some good pine in the 

 canyons. The slopes of San ..Pedro 

 Mountains bear a scattered stand of 

 red fir and yellow pine. Much of this 

 mountain has been cut over from time 

 to time to supply the mines at San 

 Pedro and Golden. With the excep- 

 tion of the areas covered by yellow 

 pine, the remainder of the additions is 

 covered with a heavy stand of juniper 

 and pinon. 



The Estancia Valley, which borders 

 the additions on the east, is rapidly 

 becoming a prosperous agricultural 

 region, and large numbers of people 

 are coming in from all parts of the 

 Middle West to take up ranches in 

 this locality. Under the new Camp- 

 bell system of dry farming there has 

 been considerable success the past few 

 years, and hence it is very important 

 that the timber and woodland em- 

 braced in the additions be protected 

 from ruthless exploitation, in order 

 that the settlers may have an abundant 

 supply of wood for fuel and posts, 

 both at the present time and in the 

 future. 



The elimination made by this 

 proclamation of all the land lying south 

 of the Belen cut-off, contains a con- 

 siderable quantity of juniper and pinon 

 timber, but on account of its isolation 

 and the great scarcity of water it does 

 not form a very important factor in 

 the timber supply of the Estancia Val- 

 ley. This area is chiefly important at 

 the present time for sheep grazing. 



The recent proclamation also added ; 

 an area of 110,525 acres to the old Mt. 

 Taylor National Forest, now Manzano . 

 No. 2. This addition is in two bodies, 

 one on the high mesa northeast of the 

 town of San Mateo, locally known as^::? 

 the Sierra Chivato, and the other on- 

 . the ridge northwest of the town of 

 San Mateo. The former lies between 

 the Cebolleta, Ignatio Chaves and
