In any attempt to secure a comprehensive variety it should be remembered that, 

 including the conifers, there are over five hundred native species in the United 

 States and Canada, and that there are over ninety in the Middle and New England 

 States. Many of these are used in forestry work, but are not adapted to streets 

 and highways ; and many others are desirable for lawns or parks but nowhere else. 

 The Elm stands first on the list by right of its superior size, beauty, and adapta- 

 bility to street planting. It is rapid in growth, withstands transplanting and prun- 

 ing better than most other kinds, and will grow on almost any soil. Its habit is such 

 that any pruning of the lower limbs is seldom necessary, a valuable feature in a street 

 tree. It thrives not only on country roads and village streets, but also in our larger 

 towns. New Haven has attained national fame as the " Elm City," on account of 

 the many beautiful trees of this kind which line its streets. There are various 

 forms of the American Elm. Emerson, in his " Trees of Massachusetts," describes 

 three distinct shapes. The most desirable one for a shade tree is that with the 

 umbrella-shaped top, and slender, pendant branches on its outer edge. In trans- 

 planting or in giving orders to a nursery, care should be taken to secure this 

 particular form. The English and Scotch Elms have been planted extensively in 

 some places ; but as these species are inferior in appearance and much more liable 

 to attack from insects their use should be discouraged. The English Elm retains its 

 foliage longer each fall, but that is all that can be said in its favor ; in fact, all the 

 species introduced from Europe hold their leaves when most of our native trees are 

 bare. 



The Hard Maple or Sugar Maple is so well and favorably known as a shade tree 

 that it is unnecessary to dwell here upon its beauty and symmetrical proportions. 

 It is seen at its best in village streets and along country roads, where the condi- 

 tions are better suited to its fullest development. In the crowded streets of large 

 towns this species, in some places, has been unable to withstand the effects of smoke, 

 dust and other unfavorable conditions. But it can be planted with good results on 

 streets where the houses stand on large lots, with plenty of ground or wide lawns
