These enumerations of the work being done by the U.N.'s program of technical assistance are a substantial and bolstering catalogue of credits in a war torn world. For while we have gone on hating each other, we have also gone on helping, now more than ever, and this often neglected fact is made clear here. In a round-the-world survey, we glimpse the deeds: the reconstruction of Cuzco, Peru and its concurrent help to the Indians; the increase in Haitian fishing; training for government in Bolivia; a whole new government in Libya; agriculture in Pakistan- and countless others. Authoritatively written, by an author with a good record of historical and biographical non-fiction, this makes a fine addition to U. N. literature for young people.
