A new method of studying underground insects, J. B. Smith (Science, n. ser., 

 8 (1898), No. 195, pp. SOS, 399).— This is an abstract of a paper read before Section F 

 of the American Association for the Advancement of Science at its Boston meeting, 

 in which the author states that plaster Paris thinned makes excellent casts for 

 studying the burrows of underground insects. If properly thinned it will follow 

 the burrow for about 6 ft. underground. In this way satisfactory studies may be 

 made of the burrows of bees, wasps, spiders, and many Coleopterous insects.
