pattern roll used in operating the three later models. All of these, 

 were devised by J. A. Groebli, son of Isaac Groebli, the inventor of 

 the Schiffli machine, and were developed and built in the shops of 

 The Kursheedt Manufacturing Co. By means of the automat the 

 movements of the fabric frame of the embroidering machine are con- 

 trolled mechanically, thereby dispensing with the pantograph oper- 

 ator and insuring greater speed, accuracy and uniformity in the 

 work. 



Of accessions other than textiles received during the year, the more 

 important were a set of specimens illustrating the manufacture of 

 featherbone from turkey feathers, contributed by The Warren 

 Featherbone Co., of Three Oaks, Mich., to replace material supplied 

 by the same firm in 1884; a collection of ostrich plumes from the 

 Cawston Ostrich Farm, of South Pasadena, Cal., forming a valuable 

 addition to the exhibit of feathers and feather work and embracing 

 every grade of raw, bleached and dyed feathers, as well as a beauti- 

 ful Knight Templar's plume; two beautifully carved mother-of- 

 pearl shells, on which are depicted the Last Supper and the Cruci- 

 fixion, lent by the Misses Long, of Washington; and specimens of 

 oak and spruce phonograph horns in intermediate and finished 

 stages, presented by Sheip & Vandegrift, of Philadelphia, Pa. 



The collection of identified woods from Panama and the Canal 

 Zone was increased by 18 specimens obtained for the Museum by Mr. 

 H. Pittier, of Washington. 



The cotton exhibits in the south hall were entirely rearranged to 

 permit of the addition of new material and to provide a more bal- 

 anced installation of the principal classes of these goods. The Lowell 

 cotton loom, in a case specially provided for it, was installed on the 

 west side of the hall near the drawing and spinning frames con- 

 tained in the western wall case. In the corresponding but larger 

 wall case on the east side of the hall were added 12 large pieces of 

 textile machinery besides a number of spinning wheels and reels and 

 numerous small models. One section of the case has been utilized 

 for the hand-operated textile machines and appliances belonging to 

 the colonial period gi the country, while the back of the case has 

 been hung with hand-woven coverlets and curtains. In the same hall 

 the commercial wool fleeces have been very compactly arranged by 

 constructing within the single case employed tiers of pigeon holes, 12 

 inches square and 40 in number. 



Two special series of fabrics have been added to the installation 

 in the east south range, one representing fabrics having a nap or 

 pile, formed by means of a special set of threads and including vel- 

 vets, plushes, corduroys and fur fabrics ; the other composed of fab- 

 rics presenting a crepe-like, wrinkled or roughened surface, produced 

 either in the weaving or finishing, including crepes, ratines, seer-
