It is finely grained, and lias a silky Lustre when polished, and 

 is extensively used dor cabinet work and in naval architecture 

 From the sap of this maple a large quantity of sugar is pro- 

 duced yearly, it having become quite an extensive industry in 

 Vermont and other parts of the country. 



This species of maple should never be planted in low, flat 

 lands, as it will not live where the soil is saturated with water 

 during the growing season. 



The undulations and inflections of fibre called curled maple 

 and bird's eye maple, are used in veneering articles of furni- 

 ture and are highly esteemed. 



The acer platanoides, or Norway maple, resembles the sugar 

 maple, but is of slow growth for the first three years from 

 planting the seed, but afterwards increases in size rapidly. 

 As an ornamental tree it has some advantages over the sugar 

 maple, its foliage being more dense, and its leaves appear 

 earlier in the Spring, and retain their verdure later in the Fall. 



Near the border of the lake, towards No. -1 gate, is a choice 

 collection of ulmus campestris, or English elm, some of which 

 have been attacked by a new comer in the small grub which 

 perforates the leaves, and makes them turn yellow early in the 

 Fall. To destroy them, I have experimented this Fall with a 

 few trees by strewing small quantities of salt around some, 

 and lime-water on others. I have been advised by Professor 

 Pike of Brooklyn to sow the ashes of burnt tobacco over the 

 ground. I intend to lav a covering on the ground of the 

 stripped stems of tobacco, such as are of no use to the manu- 

 facturer. This little pest resembles the larva of the fly. 



I think it would be well to try a few common tin lamps, 

 such as peddlers use on street corners, secure them on poles, 

 and at the proper times at night light them, which would no 

 doubt destroy many thousands of moths, and a little per- 

 severance in this experiment might be a certain cure in the 

 future. 



I have often scraped the bark of fruit trees and given them 

 a coat of whale oil soap with good results, and believe the eggs 

 which escaped the scraper were afterwards destroyed by the 

 solution washed from the trees by rain.
