 Three of those forty pieces are not found in the collection today: 5, 10 and 29 on Mrs. Stratton's December 14, 1937 "Memo of collection of Pewabic Pottery for the University of Michigan from Dr. Walter R. Parker" (Archives of American Art microfilm [AAA], reel 1013, frame 1335).
 Among the finest public collections of Pewabic Pottery are the Freer Gallery of Art, Washington, D.C., the Detroit Institute of Arts, and Albion College, Albion, Michigan.
 Although the Pottery's Day Books do not begin until October 8, 1903 (AAA, reel 1013, frame 1390), Caulkins and Perry were located in the carriage house studio at the northeast corner of Alfred and John R. Streets, Detroit, by 1901, as indicated in the Pottery's first guest book. Written inside the front cover in Miss Perry's handwriting is: "People who called at first pottery exhibition on John R. St. -- uncertain date -- from 1901 to 1905" (AAA, reel 1020, frame 1103). The years given in this exhibition for Pewabic Pottery, 1903-1969, are based on those of the Pottery's Day Books. Ella Peters' last Day Book entry on February 28, 1969, reads: "Last page/Ended up just/Right/Good bye/(1969)". Today the Pewabic Society, Inc., maintains a museum, an archive, and a sales outlet and offers exhibitions, workshops, and classes for professional and student ceramists. The building has been designated a National Landmark.
 Her parents were George R. and Julia (Dickinson) Watson. Siblings were Julia (Mrs. Slason Thompson) and Janet (Mrs. Joseph Derwin Hubbard).
 This introduction happened about 1900; see Freer to Morse, February 6, 1901, Freer Gallery of Art Archive, Freer Letterpress Book, v. 7, p. 303-04. Freer became acquainted with Morse in New York City in February 1897 through fellow collector Howard Mansfield.

 It is not known if Mrs. Stratton selected the group of forty pieces from those owned by the Parkers, or if Dr. Parker selected the objects. While some of Mrs. Parker's gift of Pewabic vessels to the University came directly to the Museum of Art after Dr. Parker's death in 1954, 38 pieces went into the custody of the College of Architecture and Design, arriving there in 1958. These pieces were transferred to the Museum in 1972 as part of a larger transfer of early 20th-century decorative arts material, including decorative and architectural Tiffany glass purchased by Emil Lorch from the Havemeyer sale of 1930 (see note 15).

 The exhibition was held February 1-27, 1938. Mary Chase Stratton exhibited ten pieces (nos. 183-192) under her name, and William B. Stratton exhibited three pieces (nos. 193-195) under his name (AAA, reel 1013, frame 1320).
 See AAA, reel 1013, frame 1118, for Mrs. Stratton's handwritten list and sketches of vessels sent to the Detroit Institute of Art for consideration, June 4, 1947.

 This technical information was provided by Ella J. Peters (1901-1994). In January 1938, Mrs. Stratton hired Ella Peters to help with the management of the Pottery and trained her in ceramic processes. Peters became Mrs. Strattons trusted assistant and confidante. By the early 1950s, Peters was carrying out the bulk of the work based on daily consultation with Mrs. Stratton. Following Mrs. Stratton's death in 1961, Peters continued the Pewabic Pottery until its operation ceased and the books were closed on February 28, 1969. I had the privilege of working with Ella for almost seventeen years. She taught me how to mix glazes and to do reduction firings, first in a Revelation Electric Kiln and later in another type of electric kiln. My work with Ella provided me great insight into Pewabic's glaze and firing processes.
