1. The Flat Top, where the blow was struck to separate the implement from the flint nodule. 2. The Bulb of Percussion caused by the blow. 3. The Conchoidal Fracture or shell-like flake. 4. The Flaking off at the back. 5. The Dorsal Ridge or Ridges. 6. The Secondary Working, round the edges. 7. The Patina or Skin, the result of exposure to the weather. In the characteristics of the New Stone Implements, or Neolithic Stones, which are found in Lincolnshire, the points to be noticed are— 1. The Definite Shaping of the Stone. 2. The Worked Edges of the Implement. 3. The Piercing or Socketing of the Stone. 4. The Patination of the Implement. THE NEOLITHIC BOATS Several boats made out of the trunks of trees have been found in the county— Two at Lincoln. One at Scotter. Two at Castlethorpe, near Brigg. One of the two boats found at Castlethorpe was an exceptionally fine specimen of the Neolithic boat craft. In length it was 45 feet, and 5½ feet wide inside, made out of an oak tree trunk. Within the boat was found a very fine polished stone axe-head. The interior of the boat showed that it had probably been charred, and scraped or chopped out with a stone hatchet. The boat is now transferred from Brigg to the Hull Museum. POTTERY OF THE NEOLITHIC PERIOD Very little pottery of this period has been found in the county. One very good specimen of a jar or vase, broken in pieces, was found by Mr. S. Maudson Grant on the sea-coast, outside the Roman Bank at Ingoldmells. This specimen is now deposited in the Lincoln Museum. NEOLITHIC BURIAL PLACES The burial places of early man in Lincolnshire must have been very numerous, judging from the remains we still have surviving to this day. These people were buried in barrows or large mounds of earth, which are called “Tumuli.” In Lincolnshire the barrows are of two classes, called Long Barrows and Round Barrows. The Long Barrow is the oldest form of interment, and belonged to the race of people called Dolicho-cephalic, or long-headed people. Sir John Lubbock says: “The Long Barrows are like the Gang-graben of Scandinavia, in which the dead are buried and not burnt.” It is in the _Long_ Barrows that we find this Neolithic race of people buried their dead in Lincolnshire. One of the Long Barrows still exists at Swinhope, near Grimsby, and there are others in different parts of the county. In a map of Lincolnshire, published about 1570, by Saxton, the position of some of the barrows was indicated. From that map we have compiled the following list, but the list includes both kinds of barrow, long and round—there being no indication on the map to distinguish the one form of barrow from the other:—
