This work has been taken up by Dr. U.B. Mathur, Deputy Census Superin­ tendent of Rajasthan. For the first time, basic information relating to this backward section of our society has been presented in a very comprehensive form. Short and compact notes on each individual caste and tribe, appropriately illustrated by maps and pictograms, supported by statistical information have added to the utility of the publication. One can have, at a glance. almost a complete picture of the present conditions of these backward communities. The publication has a special significance in the Gandhi Centenary Year. The publication will certainly be of immense value for all official and Don­ official agencies engaged in the important task of uplift of the depressed classes.
