 That Bit of Butter Left on Your Plate 

 — What Eecomes of It? 



THERE are about sixty-four individual 

 helpings of butter in a pound, each 

 helping equaling about one fourth of an 

 ounce. If the accumulated "scrapings" 

 from the butter-plates after the meal were 

 estimated there would probably be about 

 one "pat" collected each day, in the 

 average household. 



But if every one of our 20,000,000 house- 

 holds should waste one fourth of an ounce 

 of butter daily, it would mean 312,500 

 pounds a day, or 114,062,500 pounds a 

 year. To make this butter would require 

 the product of over half a million cows. 

 Even if such a waste occurred in only one 

 home out of one hundred, the waste would 

 still average over a million pounds — which 

 is intolerable to think of, when the value 

 of butter is so great intrinsically and gas- 

 tronomically, and when those bits of butter 

 might be put to such good usage if collected 

 in a crock by the cook.

This Vacuum Cleaner Is Used Like an 

 Ordinary Broom 



How Print Butter Is Shipped to 

 the Retailer 



ANEW vacuum cleaner which operates 

 wil 



ithout electricity combines the fea- 

 tures of a carpet-sweeper and ordinary 

 broom with the special vacuum feature. 

 A bellows, which is operated by the 

 backward and forward motion of the 

 cleaner, furnishes suction which draws 

 the dirt and dust up into the retaining 

 bag. 



Revolving brushes in the central 

 portion of the cleaner and a row of 

 stiff bristles around the border serve 

 to stir up the dust and loosen its hold 

 on the threads of the carpet. As the 

 particles are dislodged by the bristles, 

 the brushes sweep them under the 

 mouth of the suction tube and the 

 bellows pressure sucks them up into 

 the vacuum. In this way every 

 particle of dirt is removed. 



The work is thorough and is 

 accomplished with little effort 

 The cost of the 

 cleaner is low and 

 the operation is as 

 little complicated 

 as that of the 

 ordinary broom. * 

 The brushes may 

 be used alone.

HE wholesaler who sends his butter 

 out to the retail trade in neatly 

 wrapped pound-packages or "prints," 

 runs less risk of having his product 

 spoiled in transit than if the butter 

 were shipped in tubs. The accom- 

 panying photograph shows how 

 he manages to keep the butter 

 fresh and in shape until it is 

 delivered. Into each packing 

 box a closely covered tin 

 filled with ice is placed. 

 Around this the prints of 

 butter are packed. Then the 

 cover of the packing box is 

 nailed on. The cold air is 

 thus confined inside the box. 

 \ The ice melts very slowly, 

 so that the butter is kept firm 

 and hard for many hours. 

 Even when there are long 

 delays in transit so that 

 days instead of hours are 

 consumed, as sometimes 

 happens, the butter re- 

 mains hard and firm; 

 for if the ice should fin- 

 1 ally melt, the water in 

 the tin would still re- 

 main almost Jce-cold.
