Dear Panditji,
Towards the end of 2005, I sent faxes to the President and the Prime Minister of India
regarding the promotion of public awareness about the bird flu virus. I wanted to pre-warn
the people in India about the symptoms and precautions against the avian flu virus. There
were not any cases of bird flu in India at that time.
But, only the President's Secretariat
replied saying has been forwarded to Ministry of Environment and Forests.
But now, when Bird Flue may be spreading in various parts of country like Maharashtra and
Gujarat, the Central government has suddenly become more attentive. Why are they worried
about it at a time when the Flu has already spread? Why weren't the leaders and the
Central Government alert when it was not here and I sent them letter for some awareness
programme or at least an advertisement?

Dear Panditji,
Gobar Times is not only interesting, but much more informative than any other magazine in
its category.

Dear Panditji,
Some of your readers want to know about terracotta and clay and their environmental
friendliness. May I add a few more facts to lend strength to your wonderful response?Clay is fairly stable in an acidic medium in ambient/ sub-surface
conditions. Its performance (clay group of minerals) matches with quartz (silica). When
compared to other dominantly occurring minerals such as feldspar, plagioclase, pyroxenes
and amphibolite, natural clay is considered extremely acid tolerant. As clay is baked the
acid tolerance is further improved because of vitrification of silica, feldspar and clay
present in the artisanal raw material. A glaze or engobe further improves the acid
tolerant properties of terracotta.
Traditionally, artisanal clay is taken from a plot of agricultural field with
a fatigue in the soil column after years of cultivation. Potters have traditional rights,
in many parts of India, for the top one yard (90cms) of soil column as part of 'jajmani'.
By removing the fatigued column, the pedological process is accelerated on the exposed
surface. Silt from tanks and ponds is growingly being used these days due to gradual
collapse of jajmani.
Brick earth is an inferior variety of artisanal clay and does not require good plasticity
as easily moulded into simple geometric shapes. Large tracts of land is leased out
commercially for brick making similar to leasing of mining rights. Commercial brick
manufacturing in fertile agricultural land is causing greater damage contrary to artisanal
clay for use in terracotta.
