REPORTS ON EXCURSIONS. 371 
At DaALGaRVAN, which was next visited,a Yew tree was measured, 
and found to be 5 feet 9} inches in girth at 4 feet 8 inches from 
the ground. The ornamental garden gate beside it was much 
admired. Dalgarvan Mill was then passed, and, on reaching 
Smithstone, the boulder-clays, with the intervening sand and gravel 
beds, were examined. The exposures of these beds are rather 
limited, but there can be no doubt regarding the superposition of 
the beds, as sections of them are visible at the old limestone mine, 
and in two or three places in Bell’s “‘ Plantin’.” 
The limestone once worked here belongs to the iowa series, 
and as the beds which were seen at Monkcastle are those of the 
upper series, between the two points there must be an extensive 
break in the strata, as those present were waliing towards the dip, 
and but for this ought to have reached a higher geological horizon, 
A drizzling rain setting in, an interesting excursion was per- 
foree somewhat abruptly ended, the party returning from 
Kilwinning.
