added to the Stazione Zoologica is making 

 rapid progress. When completed the capabili- 

 ties of the institution for scientific investiga- 

 tion in connection with fishing and other ques- 

 tions will be more than doubled, and the ex- 

 tension would seem to be much wanted, for 

 during the spring months of the present year 

 no less than seventy naturalists of all nation- 

 alities were engaged in various researches, and 

 fifteen applicants had to be refused admission 

 on account of the lack of accommodation. 

 The completion of the new building, the 

 ground plan of which measures 110 by 77 feet, 

 will permit the following improvements to be 

 made: (1) The unique library of books on 

 marine biology will be brought together upon 

 the same fioor instead of being distributed in 

 various rooms; (2) laboratories and work- 

 rooms equipped under the superintendence of 

 Dr. Henze for research in the physiological 

 chemistry of marine animals will be the best 

 and largest of their kind, and will occupy the 

 second floor of the new building; (3) labora- 

 tories and workrooms for other physiological 

 work in connection with marine animals will 

 occupy the first floor; (4) a new photographic 

 and artists' room will be gained; (5) a bac- 

 teriological laboratory; (6) some thirty new 

 rooms for private study. The basement will 

 be occupied by enormous aquaria and tanks, 

 with the necessary engines for working the 

 circulating pumps and for supplying power 

 to the engineer's shop.

The policy of holding annually a meeting 

 of the principal engineers of the Reclamation 

 Service for the purpose of discussing matters 

 of administration and economies of work 

 seems to have become well established. The 

 reclamation act was signed by the president, 

 on June 17, 1902. An engineering corps con- 

 sisting of well-trained and experienced men 

 has been gradually selected through the Civil 

 Service Commission to meet the needs of the 

 service, and the work of reclamation has been 

 energetically pushed in all parts of the arid 

 region. The first conference of engineers was 

 held at Ogden, Utah, September 15 to 18, 1903, 

 in connection with the eleventh Irrigation 

 Congress. The first session of the second con- 

 ference was held at the time of the meeting 

 of the twelfth Irrigation Congress, at El Paso, 

 Texas, November 14 to 18, 1904. On this 

 occasion the principal engineers of the Rec- 

 lamation Service met prominent citizens from 

 the west and exchanged views with them re- 

 garding reclamation matters of common in- 

 terest. The conference adjourned to meet in 

 Washington in Jantiary, 1905, in order to 

 allow opportunity for other engineers to take 

 part in the discussions and to give additional 

 time for consideration of important details. 

 At the adjourned meeting in Washington a 

 number of prominent public men met the en- 

 gineers and exchanged views concerning mat- 

 ters in various states. The discussions that 

 occurred at this meeting and the papers pre- 

 sented then constitute a very valuable body of 

 material. The printed report of the proceed- 

 ings of the first conference, that at Ogden, 

 was distributed as Water-Supply and Irriga- 

 tion Paper No. 93 and was found to be 

 of great assistance to the men engaged in 

 reclamation work. On the recommendation, 

 therefore, of Mr. F. H. Newell, chief engineer.
