at which he worked up to about three years 

 ago. His work was always of the highest 

 order. His neatness and exactness in the 

 preparation of entomological material was 

 Unique and characteristic. It gained for him 

 the appointment of assistant curator in the 

 entomological department of the California 

 Academy of Sciences, where he worked up to 

 the time of his last illness. After the San 

 Francisco disaster and while the academy was 

 unsettled he received the appointment of pre- 

 parateur and assistant in the entomological 

 department of the University of California, 

 where he was known by the students as Pro- 

 fessor Fuchs. When the California Academy 

 of Sciences was again ready for his services 

 he returned to it. 



He leaves a widow, Maria Fuehs, who was a 

 typical and devoted helpmate, and who could 

 even excel her husband in the care and mount- 

 ing of the coleopterous Pselaphidse. 



In the death of Mr. Fuchs, one of the last 

 of a group of the older entomologists has 

 passed away; to this group belonged Frederick 

 Blanchard, Samuel H. Scudder, Henry TJlke 

 and Phillip E. Uhler. The younger entomolo- 

 gists of the Pacific Coast, many of whom were 

 his intimate friends, have ever been stimu- 

 lated and enthused by his earnestness and ex- 

 ample. He was a member of the California 

 Academy of Sciences, and also of the Deutsche 

 Entomologische Gesellschaft of Berlin. It 

 was he who organized the Pacific Coast Ento- 

 mological Society and was its first president, 

 a position which he held for several years. In 

 his earlier years he was similarly connected 

 with the Brooklyn Entomological Society, and 

 contributed short articles and notes to its Bul- 

 letin. In 1882, he published a synopsis of the 

 Jjucanidse of the United States.

ESTIMATES OF POPULATION 



The United States is now a country of 109,- 

 000,000 people, according to the bulletin con- 

 taining the estimates of population for the 

 years subsequent to the thirteenth census, soon 

 to be published by Director William J. Harris, 

 of the bureau of census, Department of Com- 



merce. It was prepared under the supervision 

 of C. S. Sloane, geographer. 



As stated, the estimated population of the 

 United States for July 1, 1914, will be 109,- 

 021,992. The population of the United States 

 and its possessions in 1910 was 101,748,269 ; so 

 there will have been an estimated gain of over 

 7,000,000 persons in a little more than four 

 years. The corresponding estimated popula- 

 tion of continental United States for July 1, 

 1914, is 98,781,324, as compared with the pop- 

 ulation of 91,972,266, as returned by enumera- 

 tors, April 15, 1910. This bulletin also pre- 

 sents the estimates of population in 1910, 

 1911, 1912, 1913 and 1914, for the states and 

 territories, and for cities which had 8,000 or 

 more inhabitants in 1910. 



Estimates of population are required pri- 

 marily for use in the census bureau in calcu- 

 lating death-rates and per capita averages for 

 years other than the census year. The so- 

 called arithmetical method was adopted for 

 computing these estimates. It is the simplest 

 and it has been shown by experience to come 

 nearer in accuracy in the majority of cases 

 than any other formula. It rests on the as- 

 sumption that the increase in population each 

 year since the enumeration is equal to the 

 annual increase from 1900 to 1910. 



The bulletin presents in its several tables 

 population data for the United States and its 

 outlying possessions in 1910 and 1900, with 

 estimates of the popidation July 1, 1914, 

 1913, 1912, 1911 and 1910. Similar data are 

 also presented for the different states in the 

 union. There is also presented a statement of 

 white and colored population on April 15, 

 1910, together with estimates of the white and 

 colored population as of July 1 for each of the 

 years 1914, 1913, 1912, 1911 and 1910. These 

 estimates, however, have been confined to the 

 states having a considerable proportion of 

 colored population, no estimate being pre- 

 sented for any state that did not have 50,000 

 or more colored inhabitants on April 15, 1910, 

 or at least ten per cent, of its population col- 

 ored.
