wliich is usually effected by the addition of hydrate of lime 

 during the process of evaporation. To evaporate the juice to 

 the point of crystallization it is put into large pans heated by 

 steam." 



" How much lime is used to clarify the juice ?" 



" It depends a little upon the degree of impurity in it, but 

 ordinarily about five or six parts of lime will clarify it perfectly. 

 The impurities, consisting of various substances, rise to the sur- 

 face in the form of scum and are removed. The hot juice is 

 run through animal charcoal and rendered quite colorless. 

 When concentrated sufficiently, which is known by its specific 

 gravity, it is run into moulds to crystallize." 



" What becomes of the refuse or cake, after the juice is 

 pressed out ? " 



" That is broken up and given to cattle. It is worth some- 

 thing for feeding, and in mixture, or in connection with other 

 substances possesses considerable nutritive properties." 



" What is the ordinary yield of sugar beets per acre ? " 



" Not far from twelve tons, but it varies considerably according 

 to soil and mode of cultivation." 



Thus we journeyed on towards Paris, through an interesting 

 country, stopping at Aix-la-Chapelle and other prominent towns 

 ,on the way. 



The recent growth of Paris is quite wonderful. The emperor 

 means to leave his mark upon the city, whatever may be the 

 final summing up of his eventful career. The work upon the 

 new and magnificent boulevards has called to Paris a great 

 number of mechanics, and the population has increased, while 

 that of the country has actually fallen off, it is said, during the 

 last ton years. Whether the prosperity and happiness of the 

 whole has been promoted or not, by this change, may be a 

 matter of doubt, but certain it is that all Frenchmen are proud 

 of the greatness and splendor of the capital. 



]\Iy room for two weeks was directly opposite the garden of 

 the Tuileries. The Louvre, with its rich and extensive art 

 galleries, adjoins. I will not attempt to give even a faint idea 

 of these collections, nor of those of the Luxembourg Palace and 

 its gardens, nor yet of the Hotel de Cluny, or the Palace des 

 Thermes, the most ancient |)art of Paris, peculiarly interesting 

 for its rare nicdiievul j»rod actions both of art and mechanics.
