The close proximityof the large mass of lava overlying exposed cave sandstone is worthyof note. There is also what appears to be a dolerite dyke to the south,while the soils themselves lie above Red Beds. From the hills the land slopes down to the stream at the bottomof the valley where the soil is very black; nearer the hills it is lightei-in colour and, moreover, is not uniform in tint, some areas being muchlig-hter than others. No. 608 is a composite sample of the soil nearer the hills; No. 609a composite sample of the black soil. No. 608 is underlain by a. Plate VII. The Homestead Oliviers Rust. The hills iu the background are of cave .sandstone, covered with volcanic rock,which is weathering readily. The macrocarpa cypress trees on the right are 25 yearsold, about 25 feet high, and their trunks from 10 inches to 15 inches in diameter. reddish sandy sub-soil, below Avhich is potciay. No. 608 wouldseem to be regarded as a mixed sand and turf soil : it is suitable forpotatoes and wheat The natural vegetation consists of zuur rooigras for the mostpart, together with some rooi platblaar grass. No. 609 is reckoned amongst the black turf soils; it is clayey andat a depth of about 12 feet ground water occurs. The soil is not agood potato soil, but excellent for wheat, Rooi Koren and Rooi Lamabeing the varieties best suited to it. The natural vegetation consistsof the same grasses found en the higher-lying land, but rooi platblaarpredominates, and in additioji there is a good pr
