REPORT OF NATIONAL MUSEUM, 1914. 75 



clavichords and pianos are played by means of a keyboard. The 

 highest deA'elopnient of stringed instruments is shown in the stopped 

 class, whose arrangement admits of shades of expression. The fourth 

 and last division, covering vibrating columns or currents of air, is 

 subdivided, according to the method by which the air is set in vibra- 

 tion, into flutes, whistles, etc.; horns, simple, with finger holes, keys 

 or slides; and reeds which are single or double, and further distin- 

 guished as beating reeds, free reeds, ribbon reeds, and inverted double 

 I'eeds. 



This classification is simple and easily grasped by the visitor, and 

 it will be seen that instruments which are preferred by both civilized 

 and uncivilized peoples may be grouped together and the different 

 materials and styles of art form an interesting picture. Upon no 

 other possession of man has there been a greater effort to render 

 grateful to the sight objects designed for another purpose. Es- 

 pecially w^orthy of note is an old English pipe organ which was 

 brought to the Virginia colony in 1700 for the Episcopal Church at 

 Port Eoyal, and later placed in Christ Church, Alexandria, where 

 it is thought to have been in use when Washington Avas an attendant. 

 It was subsequently taken to Shepardstown and thence to St. Thomas 

 Church at Hancock, Md., where it remained until 1906, when it 

 was presented to the Museum by the vestry.
