IF SCIENCE FICTION. August 1967. Editor: Frederik Pohl. Cover artist: Gray Morrow. Overall rating: ***

JAMES BLISH “Faust Aleph-Null.” Serial: part 1 of 3. See report following that of the October 1967 (yet to come).

ROGER DEELEY “The Trouble with Vegans.” First story. They are very clever smugglers. An old joke retold. (3)

KEITH LAUMER “Clear As Mud.” Novelette. Retief and Magnan are Terran representatives on a planet where mud volcanoes are a bad problem. And the complications arise. Fun. (3)

FRED SABERHAGEN “The Winged Helmet.” Novelette. Sequel to “Stone Man” in the May issue of Worlds of Tomorrow. The berserkers’ attacks through time are concentrated on individuals who control a great deal of the planet’s destiny. King Ay of pre-civilized times is killed, and a replacement has to be sent to maintain history. The ending is not satisfying; there may be more to come. (3)

BURT K. FILER “Paint ’em Green.” The search of “effects machines” by Terran governments brings about interference by outside interests, for a second time. (3)
