While working on a list of Baptist hymn books and hymnals, I have researched The Pilgrim's Hymnal: a Book of Choice Songs for All the Services of the Churches by William H. Crouse. Since I found little information online, I decided to post a bit of what I found and make an available record.
William Harlan Crouse was born in Randolph County, Indiana, February 23, 1874. He was baptized by the Nettle Creek Church, and ordained as a Primitive Baptist elder in 1899 in Indiana, He served churches in Indiana, then pastored in Kentucky from 1904 until he moved to Georgia in 1907. W. H. Crouse spent the rest of his ministry there. He pastored Primitive Baptist churches, edited Primitive Baptist periodicals called The Pilgrim's Banner and The Primitive Herald (which he founded in 1916), wrote several books and compiled The Pilgrim's Hymnal. Crouse followed the Progressive division of Primitive Baptists and became a leader thereof. His Pilgrim's Hymnal was the primary song book of the Progressive Primitive Baptists until eventually replaced by Hymns of Grace.
Crouse was the son of Charles and Pheriba Jane Crouse of Randolph County, Indiana. He married Lefa Lanning in Indiana in 1901. They had six children. W. H. Crouse died April 2, 1941. He and his wife are buried at the Eastside Cemetery in Statesboro, Bulloch County, Georgia.
The Pilgrim's Hymnal was first published in 1908. The first edition was published while Crouse resided in Graymont, Georgia, and (according to the listing at Pitts Library) was printed by the Armstrong Printing Company of Cincinnati, Ohio. Armstrong was a leading shape-note printer/publisher in that time. They also printed The Sacred Harp by W. M. Cooper. Crouse's book appeared in an upright SATB format with shaped notes.
In The Banner Herald's History (in Word and Picture) of the Progressive Primitive Baptists, John D. Durden wrote that The Pilgrim's Hymnal was "the first song book generally accepted by all our churches." The Pilgrim's Hymnal went through at least 8 editions, and the eighth edition through at least 3 printings. J. Walter Hendricks and John D. Durden bought the rights to the book in 1941 and took over publication after Crouse's death. In 1964 Robert G. Dickerson and Fred Bethea became joint owners and publishers with Durden. Robert D. Conner and George R. Daniel became owners and publishers in 1969. The Pilgrim Publishing Company, Inc. was formed by Conner, Daniel and others in 1977 and acquired the rights to the hymnal. The corporation was dissolved in 1994. Several elders involved in the production of The Pilgrim's Hymnal left the Progressive Primitive Baptists and went over to the Old-Line Primitive Baptist (e.g. Fred Bethea, Robert D. Conner, Robert G. Dickerson) -- possibly seriously undercutting its future.
Without access to several editions of the book, it is hard to determine some details about it. Based on library listings at WorldCat, apparently the first edition in 1908 had 176 pages (or more likely 176 songs). Another 1908 printing is claimed to have 205 pages, and the Primitive Baptist Library in Carthage, Illinois says their second edition holding has 245 hymns (and that hymns 1-203 have tunes and hymns 204-245 do not have tunes). Library holdings for 1936 and 1964 list 274 hymns (or 274 pages). In 1955 John D. Durden said "the present book" (copyrighted 1953) contained 359 songs, "a topical index as well as an index of titles and of first lines of the songs." His statement calls in question the accuracy of some library catalog information. The current extent of use of The Pilgrim's Hymnal is unknown to me -- except that I know of one church in Louisiana that uses it, plus the Primitive Baptist Church in Brooklet, Georgia uses it at their hymn sing (W. H. Crouse organized the Brooklet Church in 1914).
If anyone knows more details about this book, please let me know.

 "Progressive Primitive Baptists are a Christian denomination comprising 95 churches located in nine US states and one church in Haiti." This division beginning about 1910, with the main dispute being over the use of instrumental music in worship. The largest group of Progressives are in Georgia (possibly about 70%). Crouse didn't agree with all points of the Progressives, but disagreed with the Old-Line decision to disfellowship churches over these points.
