_ Number 148 August, 1926 

: On August 25th Dr, HE. A. Schwarz was retired at his own request. This 
_ is an event of historic interest because of his long and valuable services, 
_ and a deep personal interest to members of the Bureau on account of the affec- 
tionate respect in which he is held by everyone. Dr. Schwarz may truly be 
_ called a great entomologist, and his wonderful knowledge, his thorough scien- 
tific Spirit, and his helpful attitude towards the younger workers have made 
his career in the entomological service of the Government stand out above ali 
others. It would be almost impossible to exaggerate the value of his services, 
Coming to Washington in 1878, Dr. Schwarz has remained constantly in 
the Department of Agriculture except for the two years 1879-81, when Prof. 
Comstock was Chief Entomologist and Dr. Schwarz assisted Riley in the~work of 
the Entomological Commission, He has been connected with many important in- 
vestigations and has done remarkable work. His influence on his associates 
has always been inspiring and has helped greatly to strengthen all of us in 
our searchfor scientific truth, 
Fortunately, Dr. Schwarz will retain his title of Honorary Custodian 
of the Coleoptera in the National Museum, and will be found at his post as 
long as his physical condition will permit, So it is not a parting from our 
dear friend, after all. -- L. O. H. 
OF INTEREST TO AUTHORS 
In a circular for bureau editors, issued under date of August 2 by 
Dr. M. C. Merrill, Editorial Chief of Publications, a numbér of suggestions 
are offered for simplifying and expediting the preparation of illustrations. 
These suggestions are repeated in substance in an article in the Official 
Record for August 25, which all persons concerned in the preparation of manu- 
scripts are recommended to preserve for reference. Prominence is given to 
the preparation of plates, but it should be remembered that photographic il- 
lustrations are very generally published as text figures, and that plates 
(insets) are now used only in exceptional cases, A number of photographs or 
’ drawings relating to the same subject may of course be combined in a single 
text figure, as recomnended by Dr. Merrillfor plates, and even occupy, with 
a suitable legend, an entire page. -- Hd.
