Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over millions of years, these dead creatures form large deposits under sea-bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.
SOME IMPORTANT WORDS

PASSAGE
The villager has customarily been very conservative in his attitude and approach. He is reluctant to change his traditional way of thinking and doing things. His attitude, in many aspects, is : home-made is best. For instance, most cattle-farmers in the villages, prefer to feed their cows and buffaloes with a home-mix comprising local oil-seeds like mustard or cottonseed, pulses, jaggery, salt etc. It takes numerous visits, hard-convincing, daily trials and experience to convince the rural cattle farmer that compound feeds, scientifically formulated, improve the yields of milk, without any incremental costs. The age-old values and attitude towards caste, creed, woman, time and money take time to change. The villager has traditionally been a believer in the philosophy of ‘karma’ or ‘fate’. He has found it more convenient to blame his economic destitution, poor living conditions and straitened social status on ‘bhagya’, ‘karma’ or ‘fate’. The security that the villagers find in the ‘status quo’, acts as a disincentive to change and experiment, in the short run. Many of these antiquated attitudes, value-system and outlooks are changing, due to improved levels of awareness and education. However, the rate of change is sluggish. Attitudes fossilised over the centuries, do take time to change.
