Visited pasture field beyond stony field, but could not succeed in ascertaining with accuracy point whence worm ejected, often more than one hole but I could see plainly (looking only to old subsided castings) but have on side of stony field, tho a much large portion of casting almost invariably lies on lower side of orifice. Nevertheless we succeeded in measuring 3 on old pasture (New in Grozer Table)
(1) total length down slope 2.25 inches angle of slope 7°
(2) Length 2.35 ∠ = 8° 30'
(3) Length 2.10 ∠ 6° 30'
One disc, much subsided, apparently originally from 2 worms all found together was 4 1/2 inches in length down slope.
The weight of above all 3 very damp castings above Hole 447 grams
The weight of do beneath Hole grain 916 gram (without bags)
(Bag. 53 gram)
