ARBORICULTURE 



WATER POWER OF STREAMS. 



It is the regular flow of water which 

 constitutes its value as a power factor. 

 This also is controlled by the same potent 

 cause, viz., the trees at the source of the 

 streams, as is also the supply of water for 

 immense herds of stock, and household uses. 



PERMANENCE OF SPRINGS. 



A great majority of springs issuing from 



the ground all over the valleys have their 



source of supply high in the mountains, 



being led by subterranean streams to their 



point of issuance, and are regulated by the 



same laws. 



UNDERGROUND RIVERS. 



Beneath the surface, at varying distances, 

 from six feet in places to 100 feet in others, 

 along the valleys of many streams of the 

 West, there is an underflow, a broad river 

 flowing toward the oceans and gulf, from 

 which a million wells are supplied, and in 

 places the tree roots reach downward to 

 gather necessary moisture, and by capillary 

 attraction it rises to the surface moisten- 

 ing numerous agricultural crops. 



The snow upon the Rocky Mountains and 

 other ranges melting, penetrates the rocky 

 strata, percolating through the porous 



masses and flowing between the crevices of 

 rocks, through gravel and sand, may re- 

 quire years to reach the points from whence 

 the water is taken, in the Dakotas, Ne- 

 braska, Kansas and other distant states, 

 abundant at times, scarce in other years, 

 so that a short sup})ly of snow in the Rock- 

 ies may not be felt for a decade at some 

 distant point. 



ARBORICULTURE 



is thus of vast importance as a national 

 question. To solve the problems arising 

 in regard to forest perpetuation a high de- 

 gree of statesmanship will be required, men 

 who can rise superior to the petty intrigues 

 of partisan politics and in a patriotic spirit 

 look far into the future and recognize the 

 vast requirements of the nation with its in- 

 creased population half a century hence, see 

 needs of agriculture, of the manufacto- 

 ries which will soon be required to import 

 lumber from the tropics; see the demands 

 of the railways for ties and lumber, re- 

 quirements of the mines in timbers for their 

 maintenance, and with still greater vision 

 see the disastrous results of the ])resent 

 policy of forest negligence. 

 This is arboriculture. 



LETTER FROM VICE-PRESIDENT 

 BOWDITCH. 



It is not infrequently asked, " Of what 

 special use is the International Society 

 of Arboriculture? Why is it not, for in- 

 stance, better to join the American Forestry 

 Association?" The answer is a simple one. 

 "Join both if you take a wide interest in 

 the subject and can afford it," but if you 

 wish to give power and working ability to 

 John P. Brown, who really represents the 

 International Society, send your subscrip- 

 tion, whatever it may be, to him. 



Mr. Brown's name is a common one, and 

 he has the good gift of seeing and hand- 

 ling common things in a masterly way. 

 Practical, businesslike, tireless; one day 

 perhaps in California, next week in New 

 Orleans, and the following week in Boston. 

 Distance seems to lend enchantment to the 

 view, and his far-reaching grasp of the sit- 

 uation is interesting and inspiring. 



The presidents of the great railway sys- 

 tems employ him as a practical expert to 



grow and encourage growth of tie timber; 

 the large mine owners of the West accept 

 his advice on forestry matters, and these 

 two classes of men do not give ear to every 

 enthusiast who presents himself to their 

 notice, unless deep down they see the busi- 

 ness end of a plain proposition. Wherever 

 Mr. Brown appears he leaves behind the 

 mark of his individuality; a belief in the 

 man and his work. 



We all of us like to consider ourselves 

 good business men, and if we have work to 

 do we try to employ skilled assistants to 

 accomplish it, to the end that we may ob- 

 tain credit for the same, and most of our 

 best work is done for us by others in this 

 way. 



The International Society of Arboricul- 

 ture is made up almost wholly of men and 

 women who believe that Mr. Brown can and 

 will manage their public and private forestry 

 aft^airs conscientiously and well, and that 

 the whole country is the gainer by his work. 



By giving him your support you inciden- 

 tally help also other similar organizations.
