The white spruce should take the place of the Xorway for planting within 

 four or five rods of the house. It is a smaller, more compact and lighter 

 colored tree. It is not sufKciently known. The Oriental spruce is remark- 

 able for the enduring greenness of its lower limbs. Although a specimen 

 upon the grounds has been seriously scorched by two winters, 1 should regard 

 it as hardy under ordinary circumstances ; it stands here in one of our most 

 exposed places. It is a slow-growing tree. The balsam tir and black spruce 

 soon become ragged below. The hemlock should be planted behind a grouj^ 

 of trees, so as to be partially screened from sun and winds. It is then our 

 handsomest evergreen. The blue fir varies much in blueness. Seedlings do 

 not come true in this regard. The most reliable trees are secured by graft- 

 ing from the best trees. Norways are largely used as stocks. 



The arbor vita? is always desirable, although on poor soil it gets scraggly 

 in a few years. The Siberian holds its color best in winter, and on 

 the whole, is probably the best of the horticultund varieties. All these 

 varieties are small and compact, and well adapted to the immediate vicinity 

 of the house. 



The Eetinosporas or Japanese cj'presses, are dwarf, slow-growing ever- 

 greens of great merit. E. squarrosa is especially attractive. R. decussata 

 has been tried here only one winter, but it stands in a very exjiosed place and 

 does not appear to be injured. For ornamental planting the pines jirobably 

 stand in about the order named above. 



Our experience with evergreens is in favor of planting in late spring, just 

 as the growth begins.
