 the co-operation of the heads of the various departments and 

 bureaus, suitable times will be assigned, and officers de- 

 tailed, to facilitate visits to the Capitol, White House, de- 

 partment buildings, scientific bureaus, Smithsonian Institu- 

 tion, National Museum, Washington Monument, Navy 

 Yard, Naval Observatory, and other places of interest \vithin 

 easy driving distance, such as the National Zoological Park, 

 Soldiers' Home, Arlington, and Glen Echo.

 Penmar, Gettysburg, and Old Point Comfort. Details re- 

 garding these and similar excursions will be arranged, and 

 the most favorable terms secured, in order that members 

 may come to an early decision as to the trips they desire to 

 make.
