On a Central Hawke’s Bay property where subterranean clover received the usual top-dressing on one paddock and an adjoining paddock on exactly similar land received no top-dressing, the growth of the sub. clover on the former area continued for three weeks longer than on the non-dressed area. According to experts who have been investigating the world’s known resources of oil shale, should the time arrive when petroleum crude oil supplies are exhausted, there are reserves from which motor fuel can be extracted by the cracking process to operate all the motor-vehicles now registered in the world (37,000,000) for more than 400 years. The world’s potential shale oil production is estimated at 300,000 million barrels of 42 gallons. The wholesale value of the petrol consumed yearly throughout the world is about £500,000,000 and represents about one-half of all petroleum products produced annually. Heavy fuel oils constitute about one-sixth and lubricants one-tenth.
