An old friends from abroad whom I was expecting to stay with me,

telephoned me from the airport to tell me that he had arrived, I was still at the office at

that time, but I had made arrangements for his arrival. After explaining where my flat

was, I told him that I left the key under the door-mat. As I was likely to be home rather

late, I advised him to go into kitchen and help himself to food and drink.

Two hours later, my friend telephoned me from the flat. At the moment,

he said, he was listening to some of my records after having just had a truly wonderful

meal. He had found a pan on the gas stove, fried two eggs and had helped himself to

some cold chicken from the refrigerator. Now he said, he was drinking a glass of

orange juice and he hoped I would join him. When I asked if he had reached the flat

without difficulty, he answered that he had not been able to find the key under the door-

mat, but fortunately the living room window just by the apple free had been left open,

and he had climbed in. I listened to all these in astonishment. There is no apple tree in

front of my living room, but there is a one in front of my neighbor’s.

Questions :

1) Where was I when my friend arrived from abroad ?

2) Where did I tell him the key was ?

3) What did he find in the kitchen ?

4) Who rang up some time later ?

5) Where was an apple tree ?

Medical herbs also come from the forests. In the olden days our wise men and philosophers had their ‘Ashrams’ in the forests. These Ashrams were centers of knowledge and learning. Unfortunately forests were ruthlessly cut down in the past few years. While the forests are disappearing, the demand for timber is growing. We must, therefore, protect and developing our forests. ‘Van Mahotsav ’ is an important step in this direction. It is observed for a week in July everyyears. During this week lakhs of saplings are planted throughout the country. This is being done to restore our fast disappearing forests.
