species, but it frequently has a more spreading habit. It is a 

 good wood for fencing and burning, and is exceedingly tough and 

 durable. I have seen posts of this tree perfectly sound after 

 having been half a century in the ground, and I believe that 

 next to Iron Bark, there is no wood in this part of Australia, 

 more suitable for railway sleepers. The seed vessel of the 

 Hickory is very similar to that of the Grey Gum (E. tereticornis) , 

 but the rim is not so broad, nor are the valves so prominent. In 

 the swamps at Manly Beach, I have noticed a variety of the 

 Hickory with seed vessels half an inch long and two thirds 

 of an inch in diameter. This bears the same relation to the 

 ordinary forms, as the variety yrandiflom of the Red Mahogany, 

 does to E. resinifera, or the larger forms of E. licemastoma, to E. 

 micrantha. 



(17.) E. Stuartiana, in its variety lonyifolia, is the "Yellow 

 Gum 1 ' of Wingecarribbee and other parts of the interior. Sir 

 William Macarthur states that it does not exceed eighty feet in 

 height, and that the timber is " said to be good." This gum 

 bears some resemblance fo the Grey Gum and Hickory of the 

 county of Cumberland, but the leaves are generally longer and 

 more coriaceous, whilst the valves of the seed vessel are not so 

 prominent. I believe the wood is not suitable for any purpose, 

 excepting for fencing or burning. " The Bastard Box" near 

 Bathurst differs in some respects from the preceding variety, but 

 it is regarded as one of the very worst woods, for it decays very 

 soon after it has been cut, if exposed to the air. It attains a 

 considerable size, though not so large as some of the Eucalypti 

 of that district. The bark is very rough and brown, but it appears 

 subject to some variation, being sometimes coriaceous, and 

 sometimes fibrous. The Berrima variety inclines to the former, 

 and that of the mountains to the latter. A friend of mine states 

 that this gum is frequently destroyed by wet seasons. It seems 

 highly probable that under the name of E. Stuartiana, two dis- 

 tinct species are included, which hereafter must be referred to 

 separate sections. 



(18.) E. saligna is a Grey or Flooded Gum with rather a 

 drooping habit, and is remarkable for the variation in the shape 

 of the operculum, which is sometimes conical and sometimes 

 hemispherical. In the neighbourhood of Parramatta, this tree
