Why bother?
While the bell-ringers can grow annoying to some, they bring warm memories to me. One of my grandmothers (through marriage) wrote about HER mother, Amelia Kunkle, who originated that blessed bell ringing practice. From "Amelia's Story," by Martha Devine Powers (copyright 2005):
(In 1900), Cadet Amelia Kunkle found herself standing by a kettle  placed near  one of the busiest areas in New York City. The wide  stairways from the elevated came down to street level at this point. Every  hour hundreds of people passed by the place where Amelia patiently  waited. Standing by her kettle dressed in her navy blue Salvation Army  uniform and bonnet trimmed with a touch of red ribbon, skirts scraping  the sidewalk, Amelia, age 16, patiently waited for the passing throng to  drop money in her kettle. She tells her own story
one of the busiest areas in New York City. The wide  stairways from the elevated came down to street level at this point. Every  hour hundreds of people passed by the place where Amelia patiently  waited. Standing by her kettle dressed in her navy blue Salvation Army  uniform and bonnet trimmed with a touch of red ribbon, skirts scraping  the sidewalk, Amelia, age 16, patiently waited for the passing throng to  drop money in her kettle. She tells her own story 
"When I first stood by the kettle to' keep the pot a-boiling', it was  a cold day…a miserable bleak, damp day. It wasn't raining, but it  was cold, very cold. We girl cadets wore our regular shoes and long  stockings of black cotton, and over the shoes we wore rubbers over our shoes.  Our rubbers looked like slippers, but they were not lined with wool, nor  were they high-topped like galoshes or boots that people wear now.  However, we found that standing on newspapers helped insulate us from  the dampness and penetrating cold. Our usual stint of standing by the  kettle was four hours…either all morning or all afternoon…never all day. 
"I remember that I was located in New York City in what was  known as "The Battery" very near Wall Street. The exact street location  escapes me at the moment. I do remember though, that being so near the  waterfront accounted for some of the damp, cold weather. Our kettle  was strategically located at the entrance, or exit, as the case may be, to  the "El" which brought the businessmen to their jobs in the financial  district of New York. With every arrival of the "El" droves of commuters  would come surging by, some, of course, dropping their contributions in  the Salvation Army kettle.
 the businessmen to their jobs in the financial  district of New York. With every arrival of the "El" droves of commuters  would come surging by, some, of course, dropping their contributions in  the Salvation Army kettle.  
"The size of the average contribution in those days was a nickel,  a dime, or sometimes a quarter. There were not always lots of  quarters. Occasionally there might be a dollar, but not as a rule. One afternoon,  I gathered coins amounting to about eighteen dollars all told in the  kettle, which was very good for only four hours. On other days not  much happened and I was always disappointed, if that were the case." 
On one cold, winter day as the minutes passed slowly,  Amelia became restless. People were not paying attention to her, or her kettle,  as they hurried by. Only a few isolated coins lay in the bottom of her  kettle. Amelia, being Amelia, could not let this situation continue the way  it was going. One of her administrators from the Training Home,  Major Chadwell, came by to see how she was getting along. Amelia  complained to him,  
"No one is paying attention to me, Major Chadwell. I'm not  getting very much money today. What in the world can I do to make the  people notice me?" 
"Well," he said, "Why don't you find a stick and bang on the  kettle? That will draw attention to you and your kettle, Cadet Kunkle." 
"Oh, that's not very nice," Amelia replied with a frown on her  young face, "I don't think that would be a good idea at all." 
Amelia was not shy about giving her opinion at the Major's  suggestion, but the Major replied, "Well, then, Cadet Kunkle, you will  certainly  
be able to solve that problem all by yourself before long!" 
Amelia did not give up. She mulled the problem over in her mind  all that day as she stood by her kettle. By the next afternoon, before  her kettle duty began, she had her answer. 
She went to the nearby Woolworth`s ten-cent store. As she  walked up and down the aisles perusing the various items with her idea  in mind, she found just what she wanted…a small bell with a short,  dark wooden handle, not more than six inches in length over all. As  she picked it up, the little bell gave a slight tinkle. 
"What a fine tinkling sound it has," she thought. "This is just  the thing! Not too loud, but not too soft." 
The little bell cost just ten cents. 
The next day Amelia went to her kettle duty with a light heart  and happily began ringing her new little bell. Yes, of course, people  stopped and dropped coins into her kettle instead of passing her by. She  answered each contribution with a triumphant and cheery "God Bless  You and Merry Christmas."  
The idea of ringing the little bell to draw attention to her  kettle proved to be an excellent one. Amelia's idea spread like wildfire.  Very soon all the cadets had bells to ring as they stood by their kettles  collecting money for the Christmas dinner.
Worth it?
Yes. In addition to sharing the story with my girls as they dropped in all the change we'd collected on our trip, perhaps our little contribution, combined with others, helped provide meals or housing for someone in need this cold, wet, winter day.
