graceful female figiires below, forensic medi- 

 cine and hygiene, a little smaller in proportion 

 than the bust, lifting high a garland to wreath 

 it at the base of the bust. It stands in the 

 grounds of the medical school. The llikulicz 

 memorial at the surgical clinic at Breslau 

 represents in has relief Mikulicz seated in pro- 

 file, while two standing female figures, medi- 

 cine and science, of a size rather dwarfing the 

 recipient, are placing the wreath of immortal- 

 ity on liis brow. One can not help imagining 

 that Mikulicz feels rather embarrassed at the 

 situation. The Kussmaul memorial is a bust 

 rather larger than life-size hewn out of the 

 stone forming the base of the memorial, with 

 a smaller allegorical bas relief below of medi- 

 cine relieving a sick youth. The allegorical 

 design has run riot in the Virchow statue, 

 which is to be merely a statue of Hercules 

 overcoming the Nemean lion, representing 

 Virchow's conquest of disease. There is 

 nothing to suggest Virchow personally except 

 a small bas relief bust below. Something like 

 the simple grandeur and life-like presentation 

 of a St. Gauden's statue of Lincoln is what 

 the friends of the scientists long for as a much 

 more appropriate tribute to the memory of 

 men of science, perpetuating their personality, 

 but the sculptors, as a rule, seem determined to 

 insist on decorative allegorical designs. 



The government is now carrying on work 

 at regular forest experiment stations similar 

 to the agricultural experiment stations in the 

 different states. The first forest experiment 

 station created in this country was the Coco- 

 nino Experiment Station at Flagstaff, Ari- 

 zona, established last summer. Investigations 

 covering many phases of forestry in the 

 southwest have already been undertaken at 

 this station. The second forest experiment 

 station has been established this year on Pike's 

 Peak, Colorado. The need for such stations 

 becomes apparent when the long time neces- 

 sary for handling forest experiments is con- 

 sidered. In agricultural experiments definite 

 results can usually be obtained in one or at 

 most a few years; in forestry, because of the 

 long time required for trees to develop, scores 

 of years are often required to complete a 



single experiment. All experimental work is 

 conducted under the direction of men who 

 have had training in technical and practical 

 forestry, and every experiment is intended to 

 have a direct bearing upon some problem 

 which vitally concerns the management of the 

 forest. Under this system any new plan can 

 be thoroughly tried before being put into prac- 

 tise on a large scale, and thus the injury re- 

 sulting from mistaken practises can be mini- 

 mized. The greatest technical problem which 

 now confronts the forester in handling the 

 great pine forests of Arizona and New Mex- 

 ico is that of establishing a new stand of 

 trees to replace the old timber which is cut 

 off. This was the first problem undertaken by 

 the Coconino Experiment Station. Much in- 

 formation regarding the factors iniluencing 

 natural reproduction has already been secured, 

 but many years of systematic study will be 

 required to fully solve the problem. The 

 feasibility of artificial regeneration by plant- 

 ing and sowing is also being tested. The 

 latter experiments, for the sake of economy, 

 are being conducted on the smallest scale 

 which will insure reliable results applicable 

 to general conditions. The plans for the near 

 future provide for a detailed study of the 

 problems concerning the natural and artificial 

 regeneration of other commercial trees such 

 as Douglas fir, Engelmann spruce and the 

 junipers. 



Some account of the work of the Hamburg 

 Expedition to the Pacific is given in Glohus 

 and summarized in the Geographical Maga- 

 zine. Its principal field of operations has been 

 the little-known island of New Britain (New 

 Pomerania), the first crossing of which, in its 

 full width, has been effected by the expedition. 

 As mentioned in a previous note, the expedi- 

 tion, which is under the leadership of Dr. 

 Fiilleborn, has the benefit of a vessel specially 

 chartered for the purpose, and its work has 

 been greatly facilitated thereby. A prelim- 

 inary cruise along the north coast of the island 

 showed that the eastern district — that of Na- 

 kanai — which has not been supposed to extend 

 further west than Open Bay, in reality extends 

 for more than half the length of the north
