Figure 27-represents a broad chisel from village Chendagatu (police-station Khunti). It is formed of dark grey gneiss, coated with a brownish red decomposition product. The faces are flat and polished and are well rounded to meet the sides and slope gently to form a broad and slightly crescentic edge. The edge which is broken at one corner, meets the sides at sharp angles. The butt is broken and irregular. The sides which are almost parallel to each other are slightly depressed towards the middle probably to make the implement suitable for gripping. The dimensions are :-length, 10.5 cms.; breadth of the original blade, 7.5 cms.,-of the present broken blade, 5.5 cms.,at the middle, 7 cms., of the broken butt, 7 cms.; thickness of the butt, 2.75 cms. Figure 28-represents an elongated crude celt of phyllitik rock, only chipped and not polished. It was found at village Mūrūd (police-station Khunti). The edge which is crescentio is rough and irregular, and meets the sides at rounded angles, the sides taper towards a narrow and rounded butt. The faces are almost flat but are slightly rounded to meet the sides. The dimensions are:-length, 13 cms.; breadth,-of the blade, 5 cms.,-a little above the blade, 5 cms.,-of the butt, 2.5 cms. ; average thickness, 2 cms. Figure 29-shows a small polished celt from village Kākrā (police-station Ranchi). It is formed of grey compact quartzite. The straight edge is much impaired and meets the flat parallel sides in sharp angles. The sides are rough and meet the slightly convex faces at sharp angles. This specimen has the general shape of a rectangle. The thickness is greatest at the middle from which point the faces slope both ways-towards the edge and also towards the butt. The flat butt, though barely rounded to meet the faces, meets the sides at sharp angles. The dimensions are:-length, 5.5 cms.; breadth,-of the blade, 3.25 cms., of the butt, 2.5 cms.; thickness at the middle, 2 cms. Figure 80-represents a rectangular polished chisel from village Chendagutu (police-station Khunti). It is manufactured of a basaltic rock coated with a brownish red decomposition The sides, which 'are flat and product. parallel to each other are barely rounded to meet the slightly convex faces which slope both ways to form the edge and butt. The original shape of the edge which is much impaired, was probably crescentic. The butt is similar in shape to the edge, but is slightly narrower. The dimensions are:-length, 6.25 cms. ; breadth,-of the blade, 3.5 cms., of the butt, 3 cms. ; thickness at the middle, 1.4 cms. Figure 31-shows a crude chisel made of grey silicious schist, also from village Chendagutu (police-station Khunti). The polished but uneven faces are slightly convex, and slope downwards to form an irregularly rounded edge which meets the sides at widely rounded angles. The sides are unsymmetrically disposed, one being straight and the other curved and bevelled to meet the faces. The flat rough butt meets the sides almost at right angles. The dimensions are:-length, 9.5 cms.; breadth,-of the edge, 5.5 cms. ;-of the butt, 4 cms.; thickness, 1.75 cms. Figure 32-represents an unfinished celt, partly chipped and partly polished, made of brown, aonic tinted basalt. The material is much weathered, the butt is broken, and a part of the edge only recently broken. With the exception of the sharp cutting edge, the specimen appears to be unfinished. The edge is flat but slightly rounded at the corners to meet the sides which are thick, and meets the faces in slightly rounded angles. The dimensions are:-length, 135 cms. ; breadth,-at the middle, 6-5 cms.,-of the butt, 5 cms. ; thickness lower down the butt, 3.5 cms. Figure 33-represents a well-polished small triangular celt manufactured of white quartzite with red and black spots and streaks. It was found at village Bindā (police-station Khunti). It has a crescentic hatchet edge and tapering rounded butt; the convex faces almost meet in slightly flattened sides. The butt, sides and edge form one continuous uninterrupted band. The specimen is perfectly symmetrical in shape and of beautiful design and finish. It appears to have been little used. The dimensions are:-length, 6.25 cms.; breadth,-of the blade, 8.75 cms.,-of the butt, 1.5 cms.; thickness, 1.5 cms. are convex: Figure 34-represents another small hatchet, edged celt of beautiful design and finish, made of grey and white quartz rock, also from the same village (Bindā, police-station Khunti). The sides are flat and barely rounded off to meet the faces which The butt is thin and round, and forms with the sides one continuous band which terminates in sharp angles at each end of the crescentic blade. The edge is perfectly symmetrical and quite sharp. The dimensions are :-length, 3.75 cms.; breadth of the blade, 3.5 cms. ;-at the butt, 2 oms. ; thickness, 1 cm. Figure 35-represents another small highly polished hatchetedged celt made of streaked grey and whitish quartzite. The sides are unequal but well rounded, and meet the convex faces with an almost imperceptible slope. The blade is almost straight but unsymmetrically disposed between the sides which taper towards the narrow flat broken butt. The dimensions are:-length, from butt to one corner of the blade, 4.75 cms.,-from the butt to the other corner of the blade, 4 cms. ; breadth,-near the blade, 2.75 cms.,—at the butt, 1 cm. ; thickness, 1.25 cms. Figure 36-represents a chisel partly polished and partly chipped, manufactured of hornblendic gneiss, found at village Indpiri (police-station Khunti). The faces are convex and the sides which are chipped are rounded to meet the faces. The lower ends of the faces are highly bevelled and polished to form a sharp crescentic blade, one corner of which is broken. Both faces and sides converge and taper towards a narrow flat butt. The dimensions are:-length 12 cms. ; breadth-near the blade, 5 cms.,―near the butt 2.5 cms. ; thickness, 2 cms. Figure 37-shews the broken upper half of a chisel with thick rounded sides and pointed butt, from village Buruhatu (police-station Khūnti). It is manufactured of silicious slate. One of the faces is flat and the other convex. Towards the middle of the sides there are two or three depressions making the instrument suitable for gripping. Figure 38-represents a chisel, partly polished and partly chipped, made of grey quartzite and found at village Soparom (police-station Ranchi). The faces are slightly convex, being polished and bevelled towards the lower ends to form a crescentic blade. The rough and slightly rounded sides are formed by chipping out the faces, and meet the blade at round corners. The butt is broad and rounded. The dimensions are :-length, 9.6 cms.; breadth,-near the blade, 5.3 cms.,-near the butt, 3 cms. ; thickness, 2 cms. Figure 39-represents the broken upper half of a chisel manufactured of dark compact gneiss, from village Sopārom (police-station Ranchi). The faces which are very thin and almost flat, are bevelled at the borders to form a crescentic blade and slightly rounded sides. The edge and sides are quite unsymmetrically disposed. Figure 40-represents a long triangular chisel manufactured of dark grey pyroxine or amphibole gneiss, and found at village Chendagutu (police-station Khunti). The faces are polished but uneven with cleaved depressions. The sides are chipped to meet the faces. One of the faces is much more convex than the other. The faces meet to form a crescentic blade much impaired through use. The butt is rather pointed, though partially broken. The dimensions are :-length, 17 cms., breadth near the blade, 7.5 cms.; thickness, 3.5 cms. Figure 41-represents another chisel celt manufactured of compact gneiss, from village Chendagutu (police-station Khunti). It is triangular in shape, and its thickest portion is just above the edge. The butt is slightly broken, the sides are roughly polished to meet the faces which have a cleaved surface. The faces are flat and polished and bevelled to form a crescentic edge one corner of which is partly broken. The butt too is slightly broken. The dimensions are:-length, 4.65 cms. maximum breadth near the blade, 6.25 cms., thickness, 7 cms. Figure 42-represents a thick, heavy grinder manufactured of compact silicate (chert) found at village Bichna (policestation Khúnti). It is cylindrical in shape and not perfectly rounded. One end bears marks of use and the other is broken. The dimensions are :-length, 15 cms.; breadth, 9.5 cms.; thickness, 8 cms. Figure 43-represents a polished and well-finished chisel formed of dark grey gneiss, also from village Bichna. The faces which are convex slope on all sides, forming the crescentic edge which is impaired through use. The thick and flat sides are bevelled to meet the faces. The sides and faces converge towards a flat irregular butt. The dimensions are :-length, 9 cms.; breadth,-near the blade, 5 cms.,-near the butt, 2-25 cms.; thickness, 1·75 cms. Figure 44-represents the broken lower half of a polished chisel manufactured of grey compact fine-grained quartzite. It was found at village Būrūhātū (police-station Khunti). The surface is coated over with buff-coloured decomposition product. Both the faces are highly convex and slope towards the crescentic edge. The sides are flat and meet the edge at sharp angles. The dimensions are :-length, 5 cms.; breadth,-of the blade, 5 cms., at the other end, 4.25 cms. ; thickness at the broken end, 2.75 cms. Figure 45-represents a broken chisel of dark grey compact diorite gneiss, found at village Soparom (police-station Ranchi). The faces are convex and imperfectly polished. The sides are rounded to meet the faces, and converge towards the butt which is broken so that the specimen is without its upper portion. Towards the middle there are depressions on both the sides so as to render the instrument suitable for gripping. The blade which is crescentic in form is much impaired and broken. The dimensions are :-length, 11 cms. ; breadth,-of the blade, C-25 cms.,-of the broken butt, 4.5 cms.; thickness, 2 cms. |
