That Tonto Mine in Poncha Pass (p. 46, May edition) would draw 109.57 million gallons of water over 25 years @500 gal/min., not 15.6 M, my hp-28C tells me. BTW I can't read the fine print in the "Public Notice" sign on that gate in the picture.
I notice on your adless back cover: "U.S. Potage Paid". Hm, I don't think your magazine is potable, though the US Snail got it here OK. Haven't tried boiling it up for tea or soup yet though I enjoyed reading it.
