Sliding Scale or Double Guarantee. 



The law definitely provides that the manufacturer shall 

 state only the minimum percentage of protein, fat and carbo- 

 hydrates upon the guarantee. The object of this is to prevent 

 the purchaser from being misled by a double guarantee. For 

 example, without this provision in the law, when a guarantee 

 shows 30 per cent to 45 per cent protein, an analysis of 30 

 per cent "is all that is necessary to meet the guarantee, although 

 the guarantee may lead the purchaser to believe that he may 

 get close to 45 per cent, when as a matter of fact he is more apt 

 to get 30' per cent, or ev^n less. The last year has shown a 

 marked improvement in this regard. In 1919, out of 306 

 samples analyzed, 34, or 11 per cent, had a double guarantee, 

 while in 1920 out of 340 samples only 21, or G per cent, had a 

 double guarantee. These cases were brought to the attention 

 of the manufacturer and in most cases old tags had been used. 

 All of these manufacturers have promised to comply with the 

 law in the future.
