RADIATION OF HEAT. 



There is no doubt but what some trees emit more heat than others, and it would 

 be a matter of much interest to know just what varieties are the most valuable in 

 this respect. Will a tree carrying double the amount of leaves of another have any 

 advantage in this respeci? 



Some twenty years ago, Andrew S. Fuller said: "The pines of our southern 

 states furnish immense quantities of fuel, pitch, tar, resin and turpentine, and so 

 great is the production of the last named articles, that we have exported in a single 

 year more than a million dollars worth, besides the vast quantities used at home." 

 But we need pines in the north for fuel much more than they do in the south, and 

 we can grow them just as readily as they can. Winters like 1884-85, when it gets 

 Intensely cold, especially on the open prairies, we need fuel that will produce in ■ 

 intense heat in just the shortest possible space of time, and the different varieties 

 of pitch pine will do it. Pinus Regida is found in nearly every state in the Union, 

 and is one of the best for this purpose. Pinus Resinosa is good. There is a pine 

 found on the Blue Mountains of Oregon in latitude 46° that is equal to our pitch 

 pine in resinous matter, it may prove the same.

I desire to ask your indulgence for a moment. 



About a score of years ago a little band of public spirited men joined 

 together in laying the foundations of this Society. Its beginnings 

 were feeble, but it has survived the dangers of its infancy and is now 

 what we see it, a robust and vigorous youth, full of promise, and is 

 doing more than any other organization in the State to kindle and to 

 gratify horticultural tastes and to elevate Horticulture as a profession. 

 It has been my happy privilege to put in some of the best energies of 

 my life to develop the resourses of the great State of Minnesota and 

 to improve its horticulture. I have been in my humble way an ad- 

 vocate of home adornment and of the supplying of the tables of our 

 people with an abundance of fruits. and vegetables of every kind, of
