A formidable piece of fictionization of the story of rubber through two centuries (and some 600 pages), cleverly constructed, many faceted and generally good entertainment. Many countries, many lives and loves, are related to this substance which has led to so much greed, exploitation and bitterness. A rubber tapper in Brazil; an English gardener sent to Ceylon with the first rubber seedlings; Bancroft, Goodyear's friend; a rubber worker in Akron; a planter; an industrialist; a company stool sent out to the Dutch East Indies; a chemist who sabotages the product of the I.G. Farben buna plant; Washington and a Senate investigation; the hold-up of synthetic rubber and the bungling of allocations -- right up to the minute, against a background of two hundred years of history. There is adventure, there is romance -- the whole a more ambitious work than any she has attempted -- in the Grand Hotel manner, cross sectioning an industry. She has an established market. This is, perhaps, a trifle above that level.
