Some Earth Theories in Relation to Engineering Practice:- Discussion on Col. Moncrieff's Paper

The CHAIRMAN said it. did not need any words from him to express the appreciation they all owed to Colonel Moncrieff for his very lucid and interesting lecture, because the acclamation of the audience had indicated what they felt. But he asked them to accord Colonel Moncrieff a very hearty vote of thanks for the great kindness he had shown in presenting this lecture and giving them such very interesting diagrams to illustrate it. Colonel Moncrieff had crystallised a very large subject extraordinarily well, and to have given the audience the results in a very lucid form. He (the Chairman) would like to say a few words in reference to some remarks Colonel Moncrieff had made, and the first of these was in relation to the application of sand to the stuff that had been ca1led “porridge.” He happened to have at the present moment a rather interesting problem of somewhat similar material to what Colonel Moncrieff had found in Norway, where under certain circumstances the ground would stand at an angle of 90 degrees to the horizontal, but after a shower of rain it was turned to “ porridge ” and lay down to 1 in 12, or something of that order. The problem was to form open cuts 30 or 40 ft. deep of a considerable width, and to ensure that the sides would not fall in. He had been extraordinarily interested and flattered really to find that the experience of Colonel Moncrieff had coincided exactly with what he intended to do, namely to cover over the slopes with sand or quarry refuse, and in addition to make provision for draining the ground. He would not say more because he knew there were a number of members present who wished to speak, and he would like to hear them.
