American enterprise took up the new industry, and it 

 developed steadily. However, it was not until after 1890 

 that the rapid growth began. Since that date the business 

 has been growing with increasing rapidity, aided, to some 

 extent, by the perfection of artificial refrigeration. This 

 provided a way for these frozen dainties to be used in the 

 south, and made possible the great wholesale factories 

 found in some of our large cities. 



The value of the ice cream consumed in this country 

 has reached the enormus figure of $i5o,ooo,ooo 1 per annum
