therefore very small. Unfortunately, 

 the quality of the water at a depth of 

 35 feet below the surface was found 

 to be very salty, and the water contin- 

 ually increased in saltiness until at 

 50 to 60 feet it was about as strong 

 as sea-water. For this reason the un- 

 derflow at this point is of little or no 

 value. 



A large number of tests of pumping 

 plants in the valley of the Rio Grande 

 were made, and the cost of irrigation 

 by use of well water was carefully 

 determined. The average cost of wa- 

 ter from the pumping plants was about 

 five dolars for each acre of water one 

 foot deep. Test wells were drilled 

 near Las Cruces, New Mexico, by 

 means of which a determination was 

 made of how much water could be 

 safely drawn from the water-bearing 

 sands and pravels of the valley with- 

 out overdrawing upon the available 

 supply. 



Pike's Peak 

 Polytechnic 

 Society. 



This Society is com- 

 posed of Civil Engi- 

 neers and Surveyors, 

 Mining Engineers, Mechanical En- 

 gineers, Electrical Engineers, Archi- 

 tects, Irrigation and Forestry Engi- 

 neers, Geologists, Assayers, Chemists 

 and others who are studying or prac- 

 ticing along technical lines. 



Its object is the promotion of inter- 

 course, observation and records in 

 technical subjects, by means of period- 

 ical meetings, reading of papers, dis- 

 cussion, special investigation into mat- 

 ters of public and technical interest, 

 the publication of such parts of the 

 proceedings as should be deemed ex- 

 pedient, providing the convenience of 

 a library and reading room for its 

 members and the colletcion of books 

 and periodicals on technical subjects. 

 It is also the intention to secure the 

 services of prominent specialists in 

 various technical branches represent- 

 ed by the Society, to lecture before the 

 members of the Society and invited 

 guests. 



The regular meetings are held on 

 the second Saturday of each month in 

 the Society's rooms in Coburn Library 



on the Colorado College campu>. The 

 annual dues for resident members are 

 five dollars and for non-resident mem- 

 bers, three dollars. There are at pres- 

 ent eighty members in good standing. 

 The following officers will serve for 

 the year 1905 : President, William 

 Strieby ; vice-presidents, B. H. Bryant, 

 L. E. Curtis, W. F. Douglas ; record- 

 ing secretary, E. A. Sawyer : corre- 

 sponding secretary, W. D. Waltman;

On December i, 1904, Professor W. 

 G. M. Stone, president of the Colo- 

 rado Forestry Association, delivered 

 an illustrated lecture on the "General 

 Subject of Forestry." January 14, 

 1905, a general discussion on "Under- 

 ground Waters" was led by Mr. E. C. 

 van Diest, E. M. and Professor J. H. 

 Kerr. On January 28, 1905, Mr. 

 Clyde Leavitt, Government Forester, 

 delivered an interesting lecture on the 

 "Forestry Movement." A memorial 

 is being prepared for presentation to 

 the Colorado Legislature, urging the 

 passage of the new forestry bill now 

 before that body. 



Any questions in regard to the So- 

 ciety or to technical matters in general 

 in Colorado, will be cheerfully ans- 

 wered by the recording secretary or 

 the corresponding secretary. 



Realizing the want of

a distinctive medium 

 estry Journal. ,. . .-, 



representing the Can- 

 adian Forestry Association, and to en- 

 list public support, that Association 

 has undertaken the publication of "The 

 Canadian Forestry Journal," with Mr. 

 R. H. Campbell as managing editor, 

 and an editorial advisory committee 

 including Dr. William Saunders, Prof. 

 John Macoun and Mr. E. Stewart. 

 The initial number of the magazine is 

 pleasing in appearance, and contains 

 several very interesting articles, to- 

 gether with a number of half-tone il- 

 lustrations. Friends of the general 

 forest movement will undoubtedly wel- 

 come this new publication. It is an- 

 other evidence of the activity of the 

 Canadian Forestry Association, and 

 a move that should not only bring
