green, changes color with approach of 

 Autumn, becoming yellow and crimson 

 of many beautiful shades. 



The Sw^eet Gum makes a very hand- 

 some street tree with good shade, and 

 has no objectionable features. 



The rapidity of growth will, to a 

 great degree, depend upon the care 

 used in transplanting and the subse- 

 quent treatment the tree receives. 



The great range of latitude in which 

 the sweet gum will thrive, and the 

 variety of soils and conditions to which 

 it accomodates itself, make this one of 

 the very best general street trees. 



Naturally, the shape of the tree is 

 conical, and it is a blunder to cut out 

 the terminal shoot for the purpose of 

 making it more spreading. 



As an ornamental shade tree, the 

 Sweet Gum is grown extensively in the 

 parks, cemeteries and on suburban 

 streets, as well as on private estates of 

 Cincinnati, Indianapolis, Louisville, and 

 all the way to Pensacola and New 

 Orleans. 



Usually it requires two or three years 

 for this tree, as well as with many 

 others, to become established so that its 

 roots may find nourishment with which 

 to build up the tree's foliage and 

 branches. This time may be material- 

 ly lessened by proper care in planting 

 in a large hole well filled with good 

 earth. 



The root system of the liquidambar 

 is thick and not of a character to be- 

 come objectionable or injurious to sew^- 

 ers. It does not sprout from roots as 

 does the abele, black locust or ailanthus. 



The tree eventually becomes a very 

 large timber tree, yet may be pruned 

 into such shapes as desired and easily 

 kept in bounds. 



This may be designated as a clean 

 tree, the foliage being easily and quick- 

 ly gathered up and removed when 



frost cuts the leaves. 



The seed is quite small, winged and 

 are contained in a peculiar, prickly ball 

 about an inch and a half diameter, 

 which is suspended by a stem four 

 inches in length, from the branches. 



The Tulip Tree. 



(Lirodendron, tulipifera) 



This immense forest tree of the 

 Middle States extending southward to 

 the Gulf of Mexico, is one of our hand- 

 some street shade trees. Primarily 

 this is, or was a great lumber tree, 

 known in the markets of the w^orld as 

 Yellow Poplar, yet it does not belong 

 to the poplar family, but to the mag- 

 nolias. 



There are many tulip trees seen on 

 the streets of our northern cities, yet it 

 is w^ell adapted to those of the South, 

 as it is indigenous to the region near 

 Mobile, Alabama, as w^ell. 



The tree is growing nicely at Den- 

 ver, Colorado, and Salt Lake City, Utah, 

 and in many eastern cities. 



Few insects disturb it, and no dis- 

 eases of w^hich w^e are aw^are. It is 

 clean, bright, and while in the forest its 

 natural growth is tall and slender, yet 

 in the streets, it spreads out into a fine 

 shape for shade 



The flowers, in Spring, resemble the 

 single yellow^ tulips, from w^hich fact 

 comes the name. 



It is readily obtainable from most 

 nurseries, w^hile in the vicinity w^here 

 there are tulip trees in the forest, the 

 small trees may be transplanted. 



Spring planting is best for this and 

 all trees of the magnolia family. 



The Tulip grows quite rapidly after 

 having obtained a good start of roots, 

 which w^ill depend upon the care used 

 in planting.
