the Merrimac valley. A fine example of the shag- 

 bark is given in "Typical Elms and Other Trees." 

 The picture is of a tree in Topsfield. 



The pig-nut (Carya porcina) grows at Harmony 

 Grove, just beyond the receiving tomb, on the left ; at 

 "Paradise" on Mason street ; at the Loringfarm; the 

 grove in South Salem ; and there is a single tree on the 

 western side of Park avenue, near the corner of Ocean 

 avenue. The bark of this species is close and resembles 

 that ot an ash. The fruit on typical trees is pear 

 shaped and smaller than that of the shag-bark. 



The mocker-nut (Carya tomeutosa) resembles the 

 pig-nut somewhat, but the young leaves and stems are 

 covered with downy hairs, and there are many more 

 leaflets on each leaf, giving the tree a heavier appear- 

 ance. It has been found sparingly in Danvers by Mr. 

 J. H. Sears, who is very familiar with the woods in that 

 region. The mocker-nut is common enough at the 

 south of us, beyond Boston. Mr. Robert Manning has 

 a tree in his garden which produced fruit in ten years 

 from the planting of the nut. 



The trees in the row along the wall separating the 

 land of Mr. Almy and others from the Hemmenway 

 property, are nearly all bitter-nut hickories (Carya 

 amara). Some of the trees are nearly nine feet in 

 circumference and it may be hoped that they will be 

 preserved, as the species is rare in this neighborhod and 

 the trees in this row are unusually large. They are 

 not likely to be broken by nut collectors as the fruit is 

 considered worthless. 



The bitter-nut hickory is quite common in the north- 

 western part of the county, and grows along North 

 street, in Danvers, and in Topsfield. The foliage is 

 finer than that of any other of our hickories.
