REPORT OF THE SECRETARY 7 



crepancy may be due to the bending and deflecting^ of the wira for- 

 merly used in sounding. All the work in this direction was accom- 

 plished by means of the echo sounding device installed through the 

 courtesy of the Navy Department. In using the sonic sounding 

 machine a vibrant note is sent out by an oscillator, which, upon 

 reaching the bottom, is reflected therefrom and caught by micro- 

 phones installed on the ship and then carried to the observer. The 

 interval between sending out the note and the arrival of the echo 

 gives data easily translated into the desired depth. By this means 

 it is easy within a limited number of seconds to determine even the 

 greatest depth found, wliich was 4,400 fathoms, that is, about 5 

 miles. Then, also, the expedition gathered samples of water from 

 various depths and temperature readings by thermometers specially 

 designed for the purpose. 



Dr. Bartsch states that " tliis expedition has been the finest in which 

 I have had the opportunity to take part. Mr. Johnson and his son 

 and the invited guests, Mr. Douglass and family, the members of the 

 staff, and every individual from the captain to the cabin stewards 

 did everything in their power to help and thus bent each moment to a 

 purpose. Aside from the splendid surroimdings in which the work 

 was done, their esprit de corps made the expedition a memorable one. 

 It will take weeks before all of the elements will have been separated 

 into the component groups, after which they will be turned over to 

 speciaUsts for report. Mr. Johnson deserves great credit for spon- 

 soring this enterprise." 



The preliminary results of this first cruise, particularly the descrip- 

 tions of the many new forms found, are now being \mtten up and will 

 be published in the Smithsonian Miscellaneous Collections. 



REMOVAL OF GELLATLY COLLECTION TO WASHINGTON 



Four years after its presentation to the American people through 

 the Smithsonian Institution, the Gellatly collection of paintings and 

 art objects was transferred from New York to Washington on April 

 30, 1933, and opened to the public in the National Gallery of Art on 

 June 23. Ralph Seymour, curator of the collection for many years 

 while it was in the possession of Mr. Gellatly, came to Washington 

 to assist in its unpacking, classification, and preparation for exhibition. 



The assembling of tliis collection, valued at more than $4,000,000, 

 formed the lifcwork of Mr. John Gellatly. It comprises more than 

 1,600 separate pieces, including 145 American paintings in oil, water 

 color, and pastel; a notable collection of paintings by European 

 masters; and many interesting and valuable examples of various types 

 of art objects, including ancient glass, jewelry, period furniture, 

 sculpture, and tapestries.
