results of experience are, therefore, strikingly corroborated by 

 the deductions of science, that the cranberry will grow where 

 nothing else will. It explains, too, how it is that this fruit 

 seems to require nothing for its perfect development, but air 

 and water, as will appear more distinctly hereafter.* 



Modes of Cultivation. — The cranberry may be propagated 

 from the seed, or from cuttings, or by transplanting. The last 

 method is most frequently adopted. The first crop obtained 

 by planting the seed, will ordinarily be a year or two later than 



* The following is a detailed statement of the analysis referred to : — 



ANALYSIS OF THE ASH OF THE CRANBERRY, (Oxijcoceus Macrocarpus.) 



The berries were dried in a steam chamber at 212° F., and from these the ash 

 determined by slow combustion in a platinum crucible. 



The qualitative analysis of the ash indicated the presence of the foUoM^ng sub- 

 stances : Potassa, soda, lime, magnesia, sesquioxide of iron, sesquioxide of man- 

 ganese, sulphuric acid, chlorine silicic acid, carbonic acid, phosphoric acid, charcoal 

 and sand. 



The quantitative analysis of the ash gave the following results : —

Determination of the Potassa. 

 0.811 grms. of ash gave 1.7917 grms. of potassio-chloride of platinum. 



Determination of the Soda. 

 .811 grms. of ash gave .5748 grms. of mixed chlorides of potassium and sodium, 

 of which . . .5477 " was chloride of potassium. 



and . . . .0271 " was chloride of sodium. 



Determinatlo7i of the Lime. 

 1.622 grms. of ash gave .2955 grms. of carbonate of lime. 



Determination of the Magnesia. 

 1.622 grms. of ash gave .3122 grms. of pyrophosphate of magnesia. 



Determinatioti of the Sulphuric Acid. 

 .4971 grms. of ash gave .0521 grms. of sulphate of baryta. 



Deterinitiation of the Chlorine. 

 .8008 grms. of ash gave .0423 grms of chloride of silver. 



Determination of the Silicic Acid. 

 4.0549 grms. of ash gave .1950 grms. of silicic acid.
