In December of 1954, Mr. and Mrs. Ruben Emrick of Conrad, Montana, found a broken sandstone object in an arroyo cut located 30 miles north of the town of Empalme near Ortiz in Sonora, Mexico (Fig. 1). They very graciously brought the artifact to the Amerind Museum for examination where it was repaired and studied. The object resembled the tubular stone pipes found in the Southwest (Figs. 2, 3). It had the exterior and inner proportions so characteristic of these pipes, which were produced by drilling out the pipe interior until it resembled a modern venturi tube having a constricted throat.
