THE BOYS' BEE-HIVE FACTORY. 



SA.^r PHILOf^OPHIZING— A GREAT SCHEME. 



SNE evening, tis our two young mechan- 

 ics sat together, planning about their 

 worlv in their little factory, Sam sud- 

 denly jumped up from the porch floor 

 where he had been sitting, and ejacu- 

 lated. '• I have got a big scheme in mv 

 head!" 



'' Well, let\s have your scheme, whatever 

 it is," said his companion. 



'• Did you ever think,"' said he with an 

 air of a philosopher, " what a vast amount 

 of power there is in wind V" 



'• Why, I have known it to blow down 

 trees ; and they say, that out in Kansas it 

 has carried barns and houses into the air, 

 and lifted little babies high above the 

 ground and set 'em down carefully upon 

 haystacks," replied .Jimmy. 



'• Where did you see that about lifting 

 babies up in the air. and letting them down 

 upon haystacks?" 



" Oh I I saw that once in a paper." 



'• At any rate," replied Sam, ''whether 

 the baby story is true or not, I think my 

 new scheme is a big one. The other morn- 

 ing, just as I was getting up," continued 

 Sam, " I saw the windmill revolving just as 

 nice as could be, and there was not very 

 much wind either. Just think of it I That 

 machine we made is using a circle of only 

 eight feet in diameter, and yet it runs our 

 buzz-saw." 



" Well, what of that ?" said Jimmy. 



•' Why, just this," said Sam, with his eyes 

 gazing up at the moon. " As I was saying 

 when you interrupted me for the third or 

 fourth time, that windmill of ours uses a 

 circle only eight feet in diameter. We will 

 suppose that a windmill ten feet furnishes 

 just one horse-power." 



" What is Sam trying to get through his 

 lieadV' said Mary, his sister. 



'' Now. you just let me alone. When 1 

 get through witii what I want to say, you 



can talk all you want to ; but I want the 

 floor just now," 



" Well, go on," said Jimmy. •• We ain't 

 stopping you.'' 



" IjCt me see ; what was I going to say ?" 

 said Sam, scratching his head. "• Oh! as I 

 was saying, our windmill usesacircleof only 

 eight feet in diameter." 



'' For pity's sake, don't say that any 

 more," remarked Mary. 



•• A windmill ten feet in diameter will 

 give one horse-power, w(m't it V Now, sup- 

 pose we should put a whole lot of windmills 

 clear across oui- farm. My ! what a power 

 we could collect, couldn't we V I would put 

 the windmills so that they would be about 

 twelve feet apart from center to center, and 

 our farm is just eighty rods across the south 

 end of it. According to that, we could put 



'' and Sam began tiguring. "' We could 



put just 210 in a row. Allowing one horse- 

 power for each windmill ten feet in diame- 

 ter, we should have all together 210 horse- 

 power. These windmills we would put 

 about 25 feet high." 



•' Oh my, my ! " replied Mary. '' Sam's 

 building castles in the air. Just you come 

 here." 



" You mean he's building windmills in 

 the air," said Jimmy. " Oh, yes !'' 



Sam was so absorbed in his new scheme 

 that he evidently did not hear them, but 

 kept his eyes gazing intently on the moon. 

 as though old Luna were revolving like a 

 windmill. 



" Who is going to furnish capital to carry 

 out your great scheme V said Mr. (4reen, 

 who" now suddenly appeared before them, 

 as he was wont to do. 



'' Why, how did you know any thing about 

 it '!*" said Sam. 



"• 1 heard Mary say something about cas- 

 tles in the air, and so I thought I would lis- 

 ten. There is no doubt that there is an im- 

 mense power in wind ; and if the compara- 

 tively small amount which passes over my 

 farm could be properly utilized, it would 

 run a large gristmill." 



" Well, pa, why couldn't v/e do it V 



'• How would "you get the power all con- 

 centrated into one shaft V You know we 

 have gusts of wind traveling. Some wind- 

 mills w ould be going, while others in the 

 line would stop ; and if the whole line of 

 windmills were belted to one shaft they 

 would be apt to conflict with each other. 

 Some would want to pull while others would 

 feel like taking a rest for a while. Another 

 objection to your scheme is the great ex- 

 pense, granting that you could overcome all 

 other objections." 



" But, pa, isn't there some way in which 

 this vast amount of power could be stored 

 up, and held as a reserve force, to be used 

 whenever required?" 



'■" There is only one way that 1 think of 

 now,'' said his father, "'After going to the 

 enormous expense of a whole line of wind- 

 mills across the farm, we should have to dig 

 an immense reservoir upon neighbor Brown's 

 hill over yonder," said he, pointing to a hill 

 about 7.5 "feet high. "I will assume that these 

 windmills could pump water from some lake 

 or river up into this large reservoir. At the
