there, owing to the gales, that sweep the busy insects away, so that they fail to find their direction home. Only in sheltered combes can they be kept.

      The much-relished Swiss honey is a manufactured product of glycerine and pear-juice; but Dartmoor honey is the sublimated essence of ambrosial sweetness in taste and savour, drawn from no other source than the chalices of the golden furze, and compounded with no adventitious matter.

      Seen from a distance, as for instance from Winkleigh churchyard, or from Exbourne, Dartmoor presents a stately appearance, as a ridge of blue mountains rising boldly against the sky out of rolling, richly wooded under-land.

      But it is only from the north and north-west that it shows so well. From south and east it has less dignity of aspect, as the middle distance is made up of hills, as also because the heights of the encircling tors are not so considerable, nor is their outline so bold.

      Indeed, the southern edge of Dartmoor is conspicuously tame. It has no abrupt and rugged heights, no chasms cleft and yawning in the range, such as those of the Okement and the Tavy and Taw. And to the east much high ground is found rising in stages to the fringe of the heather-clothed tors.

      A TOR, SHOWING WEATHERING OF GRANITE

      Dartmoor, consisting mainly of a great upheaved mass of granite, and of a margin of strata that have been tilted up round it, forms an elevated region some thirty-two miles from north to south and twenty from east to west. The heated granite has altered the slates in contact with it, and is itself broken through on the west side by an upward gush of molten matter which has formed Whit Tor and Brent Tor.

      The greatest elevations are reached on the outskirts, and there, also, is the finest scenery. The interior consists of rolling upland. It has been likened to a sea after a storm suddenly arrested and turned to stone; but a still better resemblance, if not so romantic, is that of a dust-sheet thrown over the dining-room chairs, the backs of which resemble the tors divided from one another by easy sweeps of turf.

      The new Plymouth Reservoir overlies an old lake-bed. Taw Marsh was also once a sheet of rippling blue water, but the detritus brought down in the weathering of what once were real mountains has filled them all up. Dartmoor at present bears the same relation to Dartmoor in the far past that the gums of an old hag bear to the pearly range she wore when a fresh girl. The granite of Dartmoor was not well stirred before it was turned out, consequently it is not homogeneous. Granite is made up of many materials: hornblende, feldspar, quartz, mica, schorl, etc. Sometimes we find white mica, sometimes black. Some granite is red, as at Trowlesworthy, and the beautiful band that crosses the Tavy at the Cleave; sometimes pink, as at Leather Tor; sometimes greenish, as above Okery Bridge; sometimes pure white, as at Mill Tor.

      The granite is of very various consistency, and this has given it an appearance on the tors as if it were a sedimentary rock laid in beds. But this is its little joke to impose on the ignorant. The feature is due to the unequal hardness of the rock which causes it to weather in strata.

      The fine-grained granite that occurs in dykes is called elvan, which, if easiest to work, is most liable to decay. In Cornwall the elvan of Pentewan was used for the fine church of S. Austell, and as a consequence the weather has gnawed it away, and the greater part has had to be renewed. On the other hand, the splendid elvan of Haute Vienne has supplied the cathedral of Limoges with a fine-grained material that has been carved like lace, and lasts well.

      The drift that swept over the land would appear to have been from west to east, with a trend to the south, as no granite has been transported, except in the river-beds to the north or west, whereas blocks have been conveyed eastward. This is in accordance with what is shown by the long ridges of clay on the west of Dartmoor, formed of the rubbing down of the slaty rocks that lie north and north-west. These bands all run north and south on the sides of hills, and in draining processes they have to be pierced from east to west. This indicates that at some period during the Glacial Age there was a wash of water from the north-west over Devon, depositing clay and transporting granite.

      On the sides of the tors are what are locally termed "clitters" or "clatters" (Welsh clechr), consisting of a vast quantity of stone strewn in streams from the tors, spreading out fanlike on the slopes. These are the wreckage of the tor when far higher than it is now, i.e. of the harder portions that have not been dissolved and swept away.
