wondrous forest, composed of a single organic life. In the forest 

 of humanity there are master minds who compare with ordinary 

 minds as the banyan compares with ordinary trees. They occupy 

 vast space in the intellectual world, because they create and sus- 

 tain, upon a grand scale, other kindred minds, who themselves 

 take new roots and expand and grow in all directions, and yet 

 continue one with the great parent mind. There is no room 

 for base fungi where they flourish. Carlyle and Emerson are 

 specimens of this order of mind. Their influence has extended 

 far across the plains of human thought, and produced spiritual 

 fruit for the healing of the nations. HO. 



Types of Matrimonial Life. 



There are some husbands and wives whose conduct to each 

 other depends entirely upon surrounding circumstances. When 

 there is plenty of money at the bank, and prosperity is shining 

 upon the homestead, their affinity and love for each other is

 influences, they have no mutual attraction whatsoever, and their 

 affections are kept in isolation. This type of the matrimonial 

 life maybe called the .chlorine-hydrogen type. Chlorine and 

 hydrogen are gases having a powerful affinity for each other 

 that is to say, they w r ill unite when brought together in the 

 daylight ; but if we change the conditions, if we bring them to- 

 gether in the dark, their affinity is never manifested ; and thus, 

 while in the sunlight they rush together with even explosive 

 force, they will remain quiescent in the darkness, and there for 

 all eternity would form no combination whatever. PH. 



Matter is Indestructible. 



When a candle burns in the air a chemical change is going 

 on ; and although the candle disappears, the materials of which 

 it is made up are not destroyed or lost ; they simply pass into a 

 state in which they are invisible to our eyes, but their presence 

 may be ascertained by other means. Thus, if we burn a candle 

 for a few minutes in a clean bottle filled with air, and afterwards 

 pour in some clear lime-water, we shall notice that the liquid,
