anchorage length it is possible to transfer the traction forces to a predetermined depth of the subgrade. Several formalas concerning the computation of ultimate traction force are presented. 1166 HARV~,RC Q U E ~ MARY COLLEGE UNIV.LONDON, GB BURLEY, E On the behaviour and expediency of ground anchors. 16R. C IV. ~GNG, FEB. 1975, P60 -63 • 1167 SIEWI~SKI, S Interaction between point_fastenlng roof bolts and the separated rock mass. In Polish. PRZEGL. GORN,V31, N1, JAN. 1975, P15-17. The phenomenon of bolted roof layer separation is explained using the energy balance of the system supports/rock mass, and formulae for calculating the number of bolts to be inserted in roads and production workings are deduced.
Grouting and freezing i168 YAHIRO, T YOSHICA,H NISHI,K The development and practice of a Japanese grouting system. 7F, 2T, IIR. W A T ~ POW~,V27, N2, FEB. 1975, P56- 59. The authors outline the principles and practical application of a newly-developed grouting system which effectively uses a high speed w~ter or air and water Jet to break up the soil prior to grouting.

Meeting. AIME I04TH ANNUAL MEETING, NEW YORK, FEB.1975. 1170 NEALE,P The w~terproofing of earth and rockfill dams. IF. CIV.ENGNG,APR.1975,P17-23. A brief state of the art review is presented with a brief look at some of the recent more outstanding projects such as the 61 m high Manthaus dam in West Germany. Types of core and structural materials are discussed. 1171 ANONYMOUS Waterproofing with asphaltic linings and cores.6F. CY~.ENGNG, APR.1975,P27-29. Asphalt is gaining popularity as a waterproofing material for earth and rockfill dams. This short paper reviews the use of an asphaltic concrete lining on the upstream f~ce of the Dungonnell Dam, and Winscar Dam, and briefly mentions the use of asphaltic concrete cores.

This paper examines the development of design criteria for vibroflotatlon treated foundations in weak cohesive soils.

Proc. meetings held in London, Jan.1972, Sept.1972, July 1973. Edited by M.J.Jones. INSTN MIN .METALL. LONDON, 1974, 268P. Topics considered in this volume are problems of sampling in geoscience, geochemical sampling problems in the analytical laboratory, geostatistical factors in design of mine sampling programs, method of successive differences applied to mine sampling, trend analysis of alluvial deposits by Use of rolling mean techniques, general background theory of cutoff grades, the sampling and sample preparation of copper concentrator products, sampling in a primary aluminium reduction plant, and practical aspects of san~ling consignments of iron ore. 1176 BARNETT, ME IMP.

Technical note. 8F, 5R. TRANS.SOC.MIN.ENGR AIME, B,vSA,N822,MAY,1975,P53-55. An optical system, incorporating refinements of previous methods, which enables the In,mediate application of the directional information to coherent image processing is described. i177 <~ SEIB~L, wA UNIV .VI~[NA.
