Note I'-11 — Chapter I · ITINERARY: THROUGH NEW MEXICO ON THE RIO GRANDE TO EL PASO, FEB. 27TH-MAR. 21ST, 1807.

Pike has the thing all right, but under a curious name I never saw elsewhere, and might not have recognized, had I not happened to hear cojinillo myself in New Mexico. This word is probably provincial or dialectal, as it is not found in ordinary Sp. dictionaries; in form it is a diminutive of cojin, name of a certain saddle-pad or cushion, precisely equivalent to E. "pillion." It turns up now and then in books about Mexico, as for example: "The corazas [covers] of travelling saddles are also provided with several pockets called coginillos—a most excellent contrivance for carrying a lunch or a bottle, or anything to which convenient access may be desired," Gregg, Comm. Pra., I. 1844, p. 214.
