NOTES ON GEOLOGICAL RESULTS. 



Formation : After the trench had been cut it was lined 

 with stones of unequal sizes arranged as loose walls but well 

 aligned. These were plastered with a thick coating of 

 plastic clay, evidently (judging from the samples examined) 

 taken from the seashore. 



The lining of clay so formed was some two inches thick, 

 but was added to and thickened to 4 inches by the insertion, 

 all around the sides and bottom, of clay bricks previously 

 moulded and baked. These bricks had evidently been formed 

 by pressing plastic clay into spaces made by arranging 

 suitable flat stones to form moulds. The shapes were 

 repeated and there were not many. 



The bricks, in some cases, were joined together by a 

 small dowel which fitted into the sockets in the ends of the 

 bricks made by pressing the finger into the soft clay. 



That these bricks were baked before use is evident 

 from the fact that they were brick-red all through, whereas 

 the clay surrounding them was red and yellow, depending on 

 its position as regards the kiln. The coating of clay was 

 smoothed and made fairly true and had been baked into brick 

 by use. 



It was also evident that the kiln had been refaced, for 

 a thin skin of brick broke away from the older surface. The 

 heat had penetrated to a considerable depth, for only the back 

 of the clay bedding was yellow in colour. 



The floor was also clay-lined and on the bottom rested 

 a small quantity of ashes and several stones — blackened by 

 use — as heating stones. Behind the large stones were found 

 broken bricks and refuse stones and clay, the whole filling the 

 trench and supporting the sides of the Kiln, and offering 

 further evidence of the separate origin of the bricks. One 

 piece of worked flint was found by our President and a few 

 pieces of pottery, apparently of Neolithic age. It is evident 

 that before being abandoned the Kiln had been emptied. 



This form of Kiln was new to Guernsey, but, strange to 

 say, not long after Mr. S. Carey Curtis, while looking over 

 a refuse heap under the soil at Fort Grey, found some bricks 

 of almost identical shape. Specimen bricks from both 

 localities are in the Museum. 



The position at Fort Grey was visited by the Society on 

 the occasion of their excursion to Pleinmont, and other 

 specimens were collected, consisting of hand-bricks, pieces of 

 pottery and pieces of the long shaped bricks. Whether these 

 belong to the Neolithic period or not is not yet decided. On 

 comparing this one with other finds we are met with the fact
