We have a written Constitution which was adopted on 26 January 1950. Features
(a) One feature of the Indian Constitution was that it adopted universal adult franchise. All Indians above the age of 21 (now 18) would be allowed to vote in state and national elections.
(b) Our Constitution guaranteed equality before the law to all citizens, regardless of their caste or religious affiliation.
(c) The Constitution offered special privileges for the poorest and most disadvantaged Indians. The evil practice of untouchability was abolished. Hindu temples were thrown open to all, including the former untouchables. After a long debate, the Constituent Assembly also recommended that a certain percentage of seats in legislatures as well as jobs in government be reserved for members of the lowest castes, including the adivasis.
(d) Our Constitution clearly defined the powers and functions of the central and the state governments. It gave division of power in the form of three lists—a Union List with subjects such as taxes, defence and foreign affairs, which would be the exclusive responsibility of the Centre, a State List of subjects such as education and health, which would be taken care of mainly by the States, a Concurrent List under which would come subjects such as forests and agriculture in which the Centre and the States would have joint responsibility.

The arrests of the national leaders Dr Saifuddin Kitchlew and Dr Satya Pal on 10^th April 1919 in connection with the protests against the Rowlatt Act led to pervasive agitation among the people of Punjab. On 13^th April 1919, i.e. Baisakhi day, people gathered in Jallianwala Bagh to protest against these arrests. The peaceful gathering was attended by adults and children. The military commander of Amritsar, General Dyer, came to the park with some soldiers and blocked the only entrance of the park. He then ordered the men to open fire. The firing lasted for 10 minutes and killed hundreds of people and wounded thousands. People were outraged over the massacre, and there were several strikes and clashes. Martial law was proclaimed in Punjab on 15^th April 1919. Rabindranath Tagore expressed the pain and anger of the country by renouncing his knighthood.

2. Compost : Well rotted plant and animal residue is called compost.
3. Green Manuring: Shrubs like glyricidia, sesbania, karanj.

   1. Rhizobium
   2. Azotobacter
   3. Azospirillum
   4. Blue-green algae
   5. Azolla
   6. Mycorrhizae

Vermi-compost

It is the method of making compost with the use of earthworms, which generally live in soil, eat bio-mass and excrete it in digested form. This compost is generally called vermi-compost or wormi-compost. It is estimated that 1800 worms which is an ideal population for one sq. meter can feed up to 80 tones of humus per day.

During summer, we perspire more and the particles at the surface of the liquid gain energy from the surrounding or body surface and change into vapour. Now, cotton being a good absorber of water helps in absorbing the sweat and expose it to the atmosphere for easy evaporation and we feel cool.
