The mangroves regions are present near the sea coasts ,generally where the river meets the sea like the deltas formed  near the Bay of Bengal.The forests of Andamans and Nicobar Islands are also mangroves forests. These regions contain saline soil which are loose and swampy.

A trip to Jaipur part-2

Undoubtedly, to travel a long distance has its own taste.It's true that some hurdles may come the way but that also increase the excitement multifold. After a comfortable journey of some five hours I reached 'Jaipur'around 10.30PM from Sarai Rohilla.As the train rolled in the platform I got excited because a desire to see Jaipur had been simmering in me ever since I read about it in magazines and newspapers.

As ,I touched the soil of 'the pink city' it seemed dreams come true.I cannot express the feelings in words that I had at particular instant.My excitement had attained its peak.
Jaipur,also the city of forts and palaces was ready to welcome me.
It has got the name 'the pink city' as the color of the stone used in the walled city is pink.

Here, the tourists from all walks of life pay visit.
On the platform, everywhere there was a rush and a heavy flow of passengers. Holding the luggage in hand I alighted from the train and stayed at the platform for a couple of minutes, in the hope that the crowd would get reduce soon.And the same thing happened .The rush lasted for a few minutes and then everything became normal.After a while, the platform turned  almost empty .Meanwhile, my eyes searched a porter who stood some ten metres away from me .I raised and waved my hand to call him.

Thanks ,to him who understood my signs and rushed to my help.He took my luggage and stepped ahead.When I glanced at my watch ,it was around 11.30PM
Since,the arrival was at late night and I had also spent much time waiting at the platform, out the station there were only a few one and had a deserted appearance. At the parking ,I saw some engaged in gossiping. My movement drew their attention and they all turned their faces towards me .Seeing me approaching one of them stood and asked
"Sir, where to go?."
"Just need a good lodge for night stay." I replied
"Sir, please" he reciprocated.
Then, he pulled the door of the taxi and the porter kept the luggage. The driver and I got into the car.He gripped the steering wheel and put the key into the ignition and started the engine.Then he put the car into gear and turned into the narrow lane, close to the railway station where a number of lodges were available .
The taxi halted near a lodge and the driver went in .He arranged a room even at late night.
The night stay in the lodge was very comfortable .Next day early in the morning I left the bed and got ready to see the eye-catching beauty of Jaipur.
After an interval of some fifteen minutes, the noise of the car honking fell to my ears.I stepped down the stairs .Outside, the driver was waiting for me for a sightseeing tour of the palaces and the beauty of Jaipur.
The places that I visited were
Amer Fort
Hawa Mahal
City Palace
Jantar Mantar
Jaigarh Fort
