The photos above, submitted by Kris Carr, 775 N. Homer Rd., Midland, Michigan 48640, were taken at the 1991 Salt River Antique Engine and Machinery Show, held June 8 and 9 of last year. Over 250 engines and 75 tractors were on display throughout the weekend There were several toy model displays and miniature engines which were puttering away, fascinating both young and old alike. Another intriguing exhibit was Robert Jahr's water ram. The idea of the water ram dates back to the Roman Empire; the mechanism enables water to be pumped uphill without the benefit of electrical, gas or animal power. This year's Salt River show is being held on June 13 and 14, 1992. A new feature on display is a Cooper-Bessemer gas engine formerly used to operate an oil well in the local vicinity.
