We want to go on record (looking back over some 15 years of experience) in saying that we feel that A. Frederick Collins has been muddying the stream of science education too long. His latest achieves a new high in glib superficiality, archaic style, scientific inaccuracy. In less than 200 pages he ""covers"" map making, photography, electricity, radio weather, gliders, airplanes, navigation. Popularizations have their place -- but not when done with pompous ignorance in these days when the average boy in Freshman High knows oung to catch Mr. Collins in errors. Fond parents may still mistakenly fall for such books as this, but lot's hope that informed librarians and local science teachers will not provide a market.
