REPORT OF NATIONAL MUSEUM, 1924 117 



Company Association, of Mittineague, Mass.; and the Laboratory 

 Press, Carnegie Institute of Technology, Pittsburgh. 



Thirty-seven examples are now in the permanent exhibition. 

 Title pages and broadsides constitute the majority; as to qual- 

 ity, they are probably as fine as anything that has been produced. 



Besides the above-mentioned accessions, others have been received 

 from the following firms and individuals and have added to the 

 exhibits of graphic arts. 



Powers Keproduction Corporation, New York City, presented a 

 double surfaced half-tone plate and a print from it. Their invention 

 produces half-tone plates in which the parts of the plate that are to 

 print the dark masses are higher than the parts which print the 

 lighter tones, making overlay and underlay unnecessary. 



Thomson-Ellis Co., Baltimore, Md., produced and presented 

 line cuts in colors from five plates. This process requires five 

 drawings, each reproduced and printed in a different color, making 

 a strikingly interesting print. 



Jahn & Oilier Engraving Co., Chicago, 111., gave half-tone prints 

 which have a distinctive and artistic grain, the resulting print hav- 

 ing a style all its own. 



The Aquatone Corporation, New York City, has developed a re- 

 markable improvement in offset lithography, patented April 24, 

 1923, by Eobert John. In this process the half-tone reproductions 

 are made through a 400-line screen and printed on rough paper, at 

 a speed of 3,600 or more an hour, the results being so true that the 

 prints give practically all the quality of the original. Their prints 

 in line are equally fine. 



H. H. Strait, Overland, Mo., contributed an electrotype arranged 

 to show the various uses to which his reversible miniature quoins 

 are adaptable. It is an ingenious and useful article in small spaces, 

 like mortised cuts. 



Franklin T. Wood, Eutland, Mass., donated four of his etchings, 

 which are of high technical and artistic value. 



A soft-ground etching in color was the gift and work of Miss 

 Gabrielle deV. Clements, of Washington. 



Ernest Haskell, of New York, gave one of his "Flick" engraved 

 plates and a print from it. It is a remarkable piece of work in a 

 style that has not been used for several hundred years. 



Five wood engravings by Timothy Cole, the world's foremost 

 living engraver in this medium, were received during the year as the 

 result of the preparation of a biography of Mr. Cole's life and the
