A SPIDERS HUNT. 



One evening, while reading, I saw a vicious-looking spider 

 cross the table where I sat, and would have killed it at once, but 

 for the delicate sensibilities of a friend, who prevailed upon me to 

 spare its life. It was shortly out of sight, but a few minutes after 

 again appeared on the table-cover, and having reached a spot 

 near to one side, stopped, and remained perfectly motionless. 



I was curious as to its intentions, and so, apparently, was a fly, 

 which walked over to his spidership to make an examination, 

 preliminary, perhaps, to holding a post-mortem. During the 

 close examination by the fly the spider showed no signs of life, 

 until, becoming less apprehensive it got in front of his wicked- 

 looking mandibles, when he made a frantic jump for it, but the 

 inquisitive fly was too quick for him and flew off to contemplate 

 its foe from a safer distance. By this time I knew the spider was 

 on a hunting expedition and was endeavoring by a cunning 

 stratagem to get a dinner. Finding his first artifice unsuccessful, 

 the clever insect changed his tactics and began to chase full tilt 

 after the flies, hoping to capture the more unwary ones. He ran 

 with great speed to pounce upon a fly which was eating a crumb, 

 but was again disappointed by the fly taking flight. Whether 

 this predaceous spider finally succeeded in accomplishing his pur- 

 pose I cannot say, for he soon raced across the table and down 

 the other side and was seen no more.
