The general assembly of tlie state of Mary- 

 land, which has just adjourned, established a 

 State Forestry Commission, composed of seven 

 members. The governor, state comptroller, 

 the president of the Johns Hopkins University 

 and the president of the Maryland Agricul- 

 tural College and the present State Geological 

 Survey Commission comprise the new board, 

 together with the state geologist and two mem- 

 bers interested in forestry matters who are to 

 be appointed by the governor. Professor Wm. 

 Bullock Clark, state geologist, will become 

 the executive officer of the board, which has 

 the appointment of a state forester who will 

 continue the forest survey already started by 

 the State Geological Survey. The new board 

 has the right to accept as gifts and to purchase 

 lands for state forest reservations and also to 

 appoint wardens in the several counties to 

 protect the forests from fire and preserve the 

 game. 



Additional legislation was obtained by the 

 Maryland Geological Survey at the last ses- 

 sion of the legislature, providing for the con- 

 struction of a modern state road connecting 

 Baltimore and Washington. The work on 

 the road is to be taken up at once and com- 

 pleted within three years. The State Geolog- 



ical Survey has charge of all state road work 

 and under the State Aid Road Act of 1904 

 has not completed its first year's operations, 

 having contracted for about forty miles of 

 modern roads last season which are being built 

 at the joint expense of the state and counties. 

 The amount available annually for this work 

 amounts to $400,000. 



A PRELIMINARY Statement on the production 

 of hydraulic cement in the United States dur- 

 ing the calendar year 1905 has been issued by 

 the United States Geological Survey. It 

 shows that the total production of all kinds 

 of hydraulic cement in 1905, including Port- 

 land, natural-rock, and slag or Puzzolan ce- 

 ments, was 40,894,308 barrels, valued at $36,- 

 012,189. This was an increase of 9,219,051 

 barrels, valued at $9,980,269, over the produc- 

 tion of the previous year. Of the total 

 amount of cement manufactured in the 

 United States in 1905, 36,038,812 barrels were 

 Portland cement, with a value of $33,326,523 ; 

 4,473,049 barrels were natural rock cement, 

 valued at $2,413,052 ; and 382,447 barrels were 

 slag or Puzzolan cement, valued at $272,614. 



UNIVERSITY AND EDUCATIONAL NEWS. 



Mr. Andrew Carnegie has given $100,000 

 to Lehigh University for the construction of 

 a dormitory. 



A PRESS dispatch states that the movement 

 to increase the endowment of Victoria Uni- 

 versity, Toronto, by $300,000 is now practically 

 completed. That amount has been raised all 

 but $12,000, counting the $50,000 given by 

 Mr. Andrew Carnegie. The latter donation 

 was conditional upon the raising of an addi- 

 tional $50,000, but Chancellor Burwash is con- 

 fident that there will be no trouble in fulfilling 

 the condition. A new library building will 

 be erected, capable of accommodating about 

 300 students, and with a stockroom capacity 

 of 50,000 volumes. 



According to the N. Y. Evening Post Sir 

 William McDonald, of Montreal, has given 

 $55,000 for the purpose of erecting an exten-
