"Quebec City, Friday August 30 - 1929 Started out at 6:30 o'clock from an all day study of the Lapis conglomerate about to St. Joseph cemetery. First closely examined the large mass 60' along strike and 45 feet the other way. To one this mass may appear as a reef boss much larger in altitude to a long ls. It originally had an irregular surface, firstly a cauliflower like growth and maybe layers of talc or gypsum. In the hollows and finally over it lies a ls cusp. In a sandy paste that is replete with rounded large sand grains (cornithlum sand). One easily assumes that the whole ls is replete with rounded sand grain but an examination onto a close shows that weathering produces an angular or crystalline sandy like surface that is all celecite. Accordingly one is easily misled that weathering may be cephalopods makes them appear to lie in a sandy matrix. They are all in the reef ls without sand grains. The original nature of the reef ls has largely destroyed the joints and they are bombshells by weathering. In the sandy ls forms are much rarer. We have taken samples of the various kinds of ls and sands, along with some fossils other will help to explain the make up of the reef ls. Some of the hollows are filled up with finely broken ls making a cusp of small pieces. We next studied the abandoned quarry in the left ridge to the south and called locality M 15 Field. It has about
