In introducing his paper, Dr. Eastwood said that there were two principal conclusions to be drawn from the tests described in the paper. The first was that the bearing power of foundations on denx inundated sand was higher than would be expected from the usually accepted theories, and the second was that the mechanism of failure was very different from that assumed in any of these theories. Hecause of this second conclusion
it would appear that any agreement between these theories and the results of experiment was quite fortuitous, and was unlikely to hold except over a narrow range of conditions.
Pull out tests have shown that the distribution of bond stress along the column is an exponential function, and that the maximum value of bond stress occurs at the loaded end of the steel before any slip takes place, the order of the maximum value being 700 lb./in.2. After initial slip, the position of maximum bond stress moves along the steel, its value remaining sensibly constant.

Gentlemen: My first, most pleasant, and probably simplest duty this evening is to thank you and all other members of the Institution for having elected me President
for the coming year.
