The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o39。 As soon as I went outside, I forgot all about Madam Bellinsky because my wife hurried towards me. 39。Our dog, Rex, used to sit outside our front gate and bark. Every time he wanted to e into the garden he would bark until someone opened the gate. As the neighbours plained of the noise, my husband spent weeks training him to press his paw on the latch to let himself in. Rex soon became an expert at opening the gate. However, when I was going out shopping last week, I noticed him in the garden near the gate. This time he was barking so that someone would let him out ! Since then, he has developed another bad habit. As soon as he opens the gate from the outside, he es into the garden and waits until the gate shuts. Then he sits and barks until someone lets him out. After this he immediately lets himself in and begins barking again. Yesterday my husband removed the gate and Rex got so annoyed we have not seen him since.

Since then, they have been trying to find out how the fire began. Forest fire are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however, a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16,000volt power line.
