into which much more ambitious institutions had fallen. The reason is very plain to those who are familiar with Mr. Rotch's numerous visits to the best of the European central and mountain observatories. The care that he has taken to inform himself thoroughly in regard to their equipment, work and general effectiveness is clearly reflected in his printed descriptions of these institutions. By this means the youthful director of this new American observatory was enabled to take what might be termed a 'short cut' to leadership in our observational meteorology.
The regular work of the Blue Hill Observatory is carried on by Mr. Rotch with the assistance of Mr. H. H. Clayton, meteorologist, Mr.

S. P. Fergusson, mechanician, and Mr. A. E. Sweetland, observer. Not only did Mr. Rotch show excellent judgment in selecting a locality for his observatory, but he has shown equally good judgment in the choice of problems for investigation; he has taken up just those questions concerning which we have been sadly in need of numerical data, and to which every contribution is of distinct value. Moreover Mr. Rotch was exceedingly fortunate in his selection of capable co-workers, for they have responded in a notable manner to the demands which their science has made on them.
