implement swelling into an oval form, tapering to a more 

 or less narrow rounded butt at one end and to a semi- 

 circular cutting edge at the other. On the average the 

 sizes vary from 5 to 1 1 inches in length, and from 2\ to 

 4 inches in breadth. Some appear to have been formed 

 for dealing a heavy cutting blow ; other smaller examples 

 may have been employed as smoothing and polishing 

 tools, adzes, or chisels. Two celts of sandstone found at 

 Culbane are in the Darbishire collection. Another very 

 interesting example in this collection is a re-chipped 

 polished celt of felstone, which was also found at Culbane. 

 It has evidently been broken when in use, and afterwards 

 chipped away in an attempt to make some other type of 

 implement. The smallest celt in the above collection is 

 one composed of slate ; it is 2 inches long, i inch wide, 

 and |- inch thick. It has been ground all over, and was 

 found in the deposit near Culbane. A similar implement 

 of slate, but slightly larger, was found at Toome by 

 Mr. l^^ell. 



Numbers of stone celts from Toome have also been 

 described by Wilde ('57), Day ('67), and Evans ('68). 



CJiisels. — A good example of a sandstone chisel was 

 found 3 feet from the surface in peat overlying the diatom 

 deposit at Culbane, and is now in the Darbishire collec- 

 tion. It measures 6| inches long, and f inches wide, and 

 is nearly square in section. It has been ground to a 

 cutting edge at one end and smoothed on two sides. 



The greater number of the clay-slate implements have 

 a chisel-like appearance. The examples in the Darbishire 

 collection vary considerably in size and shape, but are all 

 of the same rude character, being for the most part com- 

 posed of flattish pieces of rock with one end ground 

 down to a cutting edge. The sizes vary from about 2 

 to 8 inches long, and from i to 2 inches wide, some
