24 REPORT ON AN ARBORETUM. 



at 30 feet apart, and the principal hardwood trees in the centres. 

 For the first two years the ground was kept regularly cleaned, hut 

 for the last two years only ahout eight yards in width, next to the 

 carriage-drive, has heen dressed, the plants heing closely met on 

 the rest of the ground. 



The ordinary hardwood trees, as also the spruce, larch, and Scots 

 fir, are making rapid growth ; hut it will he seen from the annexed 

 tahle that some of the ornamental varieties are doing hetter, espe- 

 cially Pieea grandis and nolrilis, Abies Douglasil and Menziesii. 

 The true pines were all very small when planted, hut they are also 

 doing well, particularly the Austrian, Corsican, ponderosa, and 

 pyrenaica. Some of the Wellingtonias had the points of their 

 lateral shoots frosted on the 8th of Octoher, and less slightly, 

 Aides Menziesii and Smithiana, Picea nolrilis and magnified. 

 Some of the Acers were also slightly touched, hut no trees appear 

 to he materially damaged, except the Wellingtonias ; however they 

 may soon regain their appearance, as the tops are not affected. 

 At the same period none of the plants in the other division were the 

 least injured. The whole of the shrubs along the side of the 

 carriage- drive, although fully exposed, are doing remarkably well ; 

 but being chiefly the same varieties as in the other division, the 

 names are not repeated in the table, as it is only for the timber- 

 producing trees that this division is noticed. 



It will be seen from the table that the coniferous trees in this 

 division are making greater top growths than in No. 1, but less 

 laterals or spread of branches. No doubt this is owing to the con- 

 finement, but as they are all taking girth of stem along with 

 top growths it will be interesting to compare and note progress. In 

 the meantime, it is well to keep in view that in Xo. 1 tbe plants 

 were much larger when planted, and all selected; while in No. 2 

 they were much smaller, and not particularly selected. The column 

 stating the cost of plants shows a great difference in original prices. 



All the trees in both divisions were planted by pitting in the 

 usual manner, without manures or artificial stimulants of any kind. 

 Owing to the ground having been trenched or ploughed, the rough 

 turf was generally brought to the surface in making the pits, but 

 it was carefully chopped up before being put into the pits again. 

 As a matter of course, the best of the sod was put next to the roots 

 of the plants, and great care was taken to place the roots at the 

 proper depth and as naturally as possible. 



The names of the coniferous plants in Xo. 1 division are shown
