It aint necessarily an easy gig, writing western history. Theres just so much cultural freight behind the genre, so much expectation. Unless youre Bernard de Voto, how do you make an appeal to the general market without losing the respect of your peers? Unless youre Wallace Stegner, how do you indulge the professorial without seeing your subject turn bland as Ovaltine? Charles G. Wormans new coffee table book Gunsmoke and Saddle Leather: Firearms in the Nineteenth- Century American West (University of New Mexico Press, $55) goes a long way toward striking that difficult balance between authenticity and amusement, elbowing its way onto the short list of entertaining texts that nevertheless manage to make some contribution to their disciplines.

Seventeen chapters and 522 pages, heavy as a gym plate and thick as a cheap couch cushion, theres no curling up in bed with this sumbitch. No, Gunsmoke is meant to be browsed, read randomly while youre hunched over your knees in the stacks, flipped through in the search for a familiar, faded face (Calamity Jane, with a Stevens pocket rifle with detachable skeleton stock.) or guns associated with famous names (This Burgess [a 12 gauge folding shotgun] passed to Pat Garrett, famed as Billy the Kids killer, who served as US customs collector in El Paso...Garrett had this gun with him when in 1908 he was gunned down by one of his tenants...) Despite the imposing size, the book is an easy way to kill an afternoon, a heavy hodgepodge of distracting tidbits. About the development of repeating rifles, for instance, Worman writes, Manufacture of the Henry repeater ceased in 1866, shortly before the demise of the Spencer. Oliver Winchester and his associates recognized the need for improvement in the Henrys magazine design. The solution was patented in May 1866 by Nelson King, a spring- tempered loading gate set in the right side of the brass frame...Loading was accomplished merely by inserting the cartridges one by one through the gate. For anyone with the least knowledge of firearms, these few sentences represent a treasure trove of learned trivia. Henrys stopped production when? And Spencers? And that side loading mechanism that you remember from Uncle Earls old 30.06? Turns out it was an 1866 patent. For a firearms enthusiast or amateur historian, anyone with the least interest in Western history, it dont get much better.

The academic value of the book arises from Wormans considerable, nearly encyclopedic expertise, his thorough knowledge of the subject. He takes a particular delight in writing captions, explaining that the fuzzy, nearly indecipherable handgun on the hip of a drover is not only being carried butt forward, but its a Colt Model 1878; that the interior of a cow punchers bunk shows us a Winchester Model 1873 rifle, a double-barrel shotgun and a holstered Colt Model 1878 revolver. A pair of hand weights on the floor beside the boots indicates the owner must have been health conscious. The various chapters, while arranged in rough temporal sequence chapter eight, The 1860s, precedes chapter nine, Trailing Cattle, and chapter eleven, The Slaughter of the Bison nevertheless can (and perhaps should) be read as stand alone essays.

This particular arena of western history, of course, is clotted with titles, each one clamoring for its share of attention. Winchester has a book, for instance. Colt has a couple, Remington. Under their own bargain imprint, Barnes & Noble has released a whole scad of coffee table browsers (A History of Arms, etc.). But Charles G. Wormans effort manages to stand out. A firearms specialist and, previously, the co- author of the two volume, Firearms of the American West, a retired deputy director of the National Museum of the U.S. Air Force and a Fellow of the Company of Military Historians, Worman is an able and entertaining guide, a scholar with no real agenda aside from the communication of his passion. His book is a skilled and valuable addition to a difficult genre.
