FORESTRY AND IRRIGATION 



May 



fully known, but it has been found 

 growing abundantly in Paloduro Can- 

 yon in Briscoe, Randall and Arm- 

 strong counties, "Texas, associated 

 mainly with the One-seed Juniper 

 (Juniperus monosperma}. The lat- 

 ter species is confined chiefly to steep 

 slopes and broken ground, while the 

 new species is spread over flat bottoms 

 and grassy mesas where there are only 

 a few inches of baked soil over rocks 

 (Fig. 4). The stems of both species 

 are easily killed by the frequent fires 

 of the region from which the One- 

 seed Juniper does not recover, grad- 

 ually disappearing from burned areas. 

 The new species, however, possesses 

 a marvelous power of sprouting from 

 charred or cut stumps, thus persist- 

 ently renewing itself and occupying 

 fire-swept localities often to the exclu- 

 sion of other woody plants. The 

 sprouts spring up in dense clusters 

 (Fig. 3) and grow rapidly for a few 

 years, and then slowly until they at- 

 tain their full height. Evidence was 

 found of the third generation of 

 sprouts, growing vigorously after fire. 



The persistent sprouting of this 

 species after fire renders it of very 

 great importance forestrally, in dry 

 regions, since it may be depended upon 

 to renew itself both after cutting and 

 burning. The wood is locally used 

 for fuel and for fence posts. 



Credit is due in this connection to 

 Mr. George L. Clothier, of the Bureau 

 of Forestry, who first observed this tree 

 in 1903, and called my atten- 

 tion to its unique and charac- 

 teristic habit of growth which 

 distinguished it from other juni- 

 pers of the region. Credit is also 

 due to Mr. H. H. Chapman of the 

 same service, who, a season later, 

 collected additional herbarium speci- 

 mens and supplied further informa- 

 tion concerning the habits and range 

 of the tree. 



This species is named in honor of 

 Mr. Gifford Pinchot, whose keen ap- 

 preciation of the importance of field 

 forest studies made possible the in- 

 vestigations which led to the discov- 

 erv of this tree. 



RECENT IRRIGATION LEGISLATION 



Resume of What Was Done at Last 

 Winter's Sessions of the Legislatures in 

 the Irrigation States and Territories 



A 



LL the Legislatures of the irri- 

 gation States and Territo- 

 ries held their binennial sessions 

 during the last winter. The interest 

 in irrigation matters in general, and 

 in the Reclamation Service in particu- 

 lar, is shown by the fact that in nearly 

 every State and Territory in the west, 

 legislation in one form or another has 

 'been passed with a view to aiding in 

 irrigation development and in the con- 

 struction of irrigation projects by the 

 Government under the provisions of 

 the Reclamation Act. 



ARIZONA. 



The Legislatures of this Territory 

 and of Kansas are among those in 

 which irrigation work is carried on to 

 any extent that do not appear to have 

 enacted legislation affecting irriga- 

 tion. 



CALIFORNIA. 



Four acts were passed by the Leg- 

 islature, involving matters concerning 

 irrigation and forestry ; namely : 



i. An act to cooperate with the 

 United States in the construction of
