and your own city. And while planting 

 trees, if you neglect the oaks, you will re- 

 gret it. 



The red oak (Quercus rubrum) is a rapid 

 growing tree- 



The pin oak {Quercus palustris)is probably 

 the finest shade and street tree of the oak 

 family. There should be avenues of oak 

 which seem to be satisfactory in Colorado if 

 not at too high an altitude. 



BLACK WALNUT. 



is growing finely at Denver, and I believe 

 it will grow well here. Walnuts are diffi- 

 cult to transplant after the first year on 

 account of the tap root being injured on 



removal. 



CHESTNUT. 



grows well in many parts of the State. 

 Only a few have been tried, but it is worthy 

 of experiment. 



To this list could be added many more 

 which have proven hardy and which should 

 be given a fair trial. 



I have no sympathy with those who say 

 that because nature did not plant certain 

 trees in a particular locality, they will not 

 grow there. This is proven false every 

 year when trees from Europe, Asia and 

 every isle of the sea are safely removed to 

 the most remote portions of the globe, 

 becoming as much at home as in their own 

 native soil. 



Plant trees. Plant a variety of trees. 

 Plant very many trees and make your city 

 one of the handsomest places on (lod's 

 footstool. 



The San Francisco Chronicle analyses 

 the bird question as follows : 



It is beginning to be evident to the most 

 obtuse, that the balance of power in nature 

 cannot be safely disturbed. If we kill the 

 birds the insects will multiply. The women 

 are the great offenders. They seem willing 

 to practice the cruelty of savages if there- 

 by they can get birds for their bonnets. 

 Sumptuary laws have never been popular in 

 America, but we may yet have to enact 

 that any woman caught with a bird on her 

 bonnet shall go to jail. 



L\ FLORIDA. 



The moist climate, warm temperature and 

 kindly sands of Florida are conducive to 

 tree growth. The live oak seldom fails to 



g^ow when taken from the forest and planted 

 upon the street or lawn. Where the 

 orange and lemon thrive, as in Florida, there 

 are very many trees which may be grown 

 as readily. 



The Catalpn speciosa makes a grand tree 

 in this State. Many thousands have been 

 planted for forest and shade about DeLand, 

 Jacksonville and elsewhere. 



The destruction of the yellow pine 

 forests by turpentine ojjerators have made 

 it imperative that other trees lie planted as a 

 protection to the citrus orchards and for 

 shade. 



The eucalyptus or blue gum of Australia, 

 may be grown in Florida and surrounding 

 States and should not be neglected. I have 

 records of growth of the eucalyptus in 

 California that are marvelous. In another 

 issue Akhoriculture will give some of 

 these measurements. 



The California Nursery Company, Niles, 

 Cal., can supply small trees of eucalyptus; 

 probably other nurseries may. They are 

 not as plentiful as they should be. Arbori- 

 culture has many friends in Florida, they 

 will not be forgotten. Each number of our 

 paper will have some contribution for their 

 benefit. 



LIRIODENDRON TULIPIFERA. 



Tulip free, yellow poplar, as it is called in 

 the lumber markets, is a grand tree for 

 street planting. The shade of green in 

 the foliage is refreshing, the fiowers are 

 prominent and handsome. Except that the 

 trees are somewhat difficult to transjjlant. 

 and require extra precaution in removal, 

 there are no objections to the tulip tree for 

 country or suburban locations. In nature 

 it is found upon the mountains and drier 

 locations, but in rich soil. It is free from 

 insects, always clean and in every way 

 desirable for shade. As a rule all the 

 magnolia family should be planted in spring; 

 for some reason autumn planting is not 

 usually successful. 



LINDEN, BASSWOOD. 



Til id Americana, and Tilia Eur apnea, are 

 both excellent street trees, the foliage is 

 dense, the head usually being sound and 

 compact, forming a perfect shade. The 

 bark is smooth, and if large trees are re-
