English elm, scarlet oak, ginkgo, red maple, bay willow. P'or coun- 

 try roadsides he recommends the tulip tree, chestnut, white willow, 

 honey locust, white oak, pin oak, sweet gum, horse chestnut, cucum- 

 ber tree, catalpa (speciosa), American larch and Ailanthus. He 

 lays great emphasis on selecting the right tree for the right place. 



Superintendent Pettigrew mentions favorably the following trees 

 as being adapted to more or less severe conditions, and best suited 

 to city planting : English elm, horse chestnut, linden, Ailanthus ; 

 while the rock, red, silver and Norway maples, the ginkgo, basswood, 

 tulip, red and scarlet oaks, cucumber tree and hackberry are better 

 suited to suburban planting. He recommends the Lombardy pop- 

 lar as an excellent tree for narrow streets, but does not recommend 

 the black or yellow locust, catalpa (speciosa) and sweet gum because 

 they are not hardy in this region ; the chestnut he does not recom- 

 mend because it is subject to fungous disease. 



Mr. Christopher Clark, the veteran city forester of Northampton, 

 values highly the rock maple, tulip, all the oaks and the elms for 

 wide streets ; and for narrow streets he recommends the Norway, 

 red and white maples, pin oak, red flowering horse chestnut, hardy 

 catalpa, Lombardy poplar and bay willow. 



City Forester \V. F. Gale, of Springfield, recommends for wide 

 streets the elm, hackberry, rock maple, tulip, white, scarlet and red 

 oaks, linden and the sycamore ; for narrow streets, the pin oak, 

 Norway, red and silver maples, sweet gum, cucumber tree, catalpa 

 (speciosa), ginkgo and red flowering horse chestnut. 



Some mention should be made of the different kinds of shrubs 

 growing along roadsides which greatly add to the attractiveness of 

 country drives, and among these may be mentioned alders, vibur- 

 nums, andromedas, clethra, cornels, New Jersey tea, sumach, spiraeas, 

 shadbush, Crataegus, witch hazel, etc. The duty of the tree warden 

 is to see that these growths are maintained and not ruthlessly de- 

 stroyed by highway surveyors who have charge of the roadbeds only. 



The aesthetic value of these natural growths, constituting as they 

 do the most charming landscape effects, is many times the economic 

 value of the land upon which they grow.
