Too Thin THERE is a Representative in Congress from the West who is exceedingly thin. Being a very good-natured man, this Representative always takes in good part any joking reference to his slenderness; indeed, he is not averse to a jest himself in that connection, as is illustrated by an incident that occurred in a strect car in Washington.
It appears that just as the car was rounding a curve a burly citizen lurched forward and sat in the Congressman's lap. He recovered himself quickly, and began a profuse apology, when he was interrupted by the statesman's cheery "That's all right."
“But,” added the Congressman, plaintively,

Vicious Inmates Some lady visitors going through a penitentiary under the escort of the superintendent came to a room in which three women were sewing.
"Dear me !" whispered one of the visitors, "what vicious looking creatures! Pray, what are they here for?"
"Because they have no other home. This is our sitting-room, and they are my wife and two daughters," blandly replied the superintendent Harper's Weekly.
There Was No Honey There They were newly married and on a honeymoon trip. They put up at a sky-scraper hotel. The bridegroom felt indisposed and the bride said she would slip out and do a little shopping. In due time she returned and tripped blithely up to her room, a little awed by the number of doors that looked alike. But she was sure of her own, and tapped gently on the panel.
"I'm back, honey; let me in,” she whispered. No answer.
"Honey, honey, let me in," she called again, rapping louder. Still no answer.
“Honey, honey, it's Mabel. Let me in!”
There was silence for several seconds; then a man's voice, cold and full of dignity, came from the other side of the door:
“Madam, this is not a bee hive; this is a bath-room !"—New York Sun.
The Perfect Lover MRS. CARRIE CHAPMAN Catt, the famous woman's rights leader, said of an untactful motion at a woman's club:
“This motion, in its delicacy, reminds me of a Ripon man.
"The man got married, and after he had been married several years his wife said to him one night:
“You do not speak as affectionately to me as you used to, Hal. I fear you have ceased to love me.'
"Ceased to love you!' growled the man. “There you go again. Ceased to love you! Why, I love you more than life itself. Now shut up and let me read the paper.'”—Philadelphia Bulletin.
