tea. Then I replaced the heads, adjusted valves, and started it up. One cylinder was very weak, - the rear one. It got too dark to work any more, but I cleaned the carburetor and decided to put in two new spark plugs tomorrow.

After dinner Ruth and I went to the library. I copied the following notes from the Handbook of St. Vincent for 1914. 

St. Vincent is 68 mi. north-north-east of Grenada, and 21 mi. southwest of St. Lucia. Its length is 18 miles, its greatest breadth 11 mi., and its area about 150 square miles. Kingstown Bay is the largest coastal indentation. The island is mostly mountainous; on the windward side there are old terraces or benches of marine erosion which form a rim of level country along the coast; on the leeward side the land slopes steeply to the sea. The highest elevation is Soufriere (4048 ft.). In the central ridge are Grand Bonhomme (3193 ft.), Marne Garu (3528), and Richmond Peak (3528). The form of all these indicates that they have suffered prolonged and intense erosion. Though of volcanic origin, none of them shows a crater or a well-preserved cone. A series of radiating valleys, very deep and narrow, has been cut into the old volcanic pile, and between these are high steep-sided spurs, the summits of which are knife-edges often only broad enough

to serve as a footpath. In the recent geological history of the island erosion has been of vastly more importance than accumulation. 

The whole of St. Vincent is of volcanic origin. There are no marine sedimentaries, and no organic limestones. Lava flows are far less important than the ash beds, but are frequently 40 ft. and sometimes 80 or 100 ft. thick, and some are nearly a mile in length. It is the alternation of ash beds with columnar-jointed lavas which yields under the influence of sub-aerial erosion St. Vincent's famous scenery. 

[[margin]] II-6-36 [[/margin]] Put the two new spark plugs in the motor hoping it would make the rear cylinder work better, but it didn't make any difference. So I took off the rear head again and ground the exhaust valve. When I got it open I saw that the piston has been leaking oil, and this was probably the [[strikethrough]] cl [[/strikethrough]] cause of the excessive carbon. The grinding improved the looks of the valve surface, but didn't help the performance of the cylinder. I couldn't think of anything else to try.

It was 10:30 by now, but I started out along the Leeward Road north from Kingstown. The hills are very steep, with frequent jagged cliffs, and the vegetation not very dense at any point and frequently rather sparse.
