requisite for their permanent improvement ; and as all soils are 

 not benefited alike by barn manures, we should call science to 

 our aid in order to discover the missing ingredients necessary 

 to constitute a fertile soil. 



In retiring from the office which I have held for three years, 

 I would tender to the trustees and members of this association 

 my grateful thanks for their uniform kindness and courtesy. 

 The interest I feel for the permanence and success of your

Respectfully submitted, 



Horace Collamore.

FOREST TREES. 



The tract of land planted to forest trees, which I entered for 

 the society's premium, payable in 1852, was a barren sandy 

 plain, remote from any habitation, and the memory of man 

 extends not back to the time when it was first reclaimed for

 I planted the then existing vacancies with white pine. In 

 March, 1845, I planted one and a half bushels of walnuts. In 

 April, 1846, I planted one bushel of walnuts, which have come 

 up well, but are of slow growth. In June, 1849, I transplanted 

 about 300 white pines, the most of which lived and are doing 

 well, but are not so vigorous as those planted in April. In 

 April, 1850, I again planted all the then existing vacancies 

 with white pines, which have generally vegetated and are 

 doing well. On this lot of six and a half acres, I have now 

 growing, something more than ten thousand trees, of various
