acres for forest plantations on their lauds, it would greatly enhance 

 the value of theii' estates, and benefit both the present and a future 

 generation. The expense of planting a few acres would not be great, and 

 the benefit thereof would no doubt be very remunerative. 



I will now point out a few varieties of such trees as are of rapid 

 growth, and suitable for this part of the country, I will say from the sea 

 coast to the foot of our mountain ranges, both North and South, from 

 Napier (on hills), either under grass or slightly covered with fern, — the 

 various sorts of pines, of which the seed could be sown where they should 

 remain, without transplanting, such as Pinus austriaca, or Austrian pine, 

 Pinus halepensis, Aleppo pine, P. maritima, P. lariceo, j^inea, jeffreyi, 

 insignis, sahiniana, torreyana, and ponderosa; various sorts of Gums, as 

 Eucalyptus globulus or Tasmanian Blue Gum, Stringy Bark, etc., Uohinia 

 pseudo -acacia (the thorny acacia), a tree of rapid growth ; the timber is 

 very strong and durable^ particularly suited for fencing-posts. Of the 

 following varieties the seeds should be sown in nursery beds, and when one 

 or two years old, transplanted ; this would be more expensive than when 

 the seed can be sown where the trees are to remain, but as these are of 

 slow growth for the first year or two, the labour of keeping them clear of 

 weeds in open plantations would be too expensive. The following would 

 be suitable, and are of rapid growth after the first two years : — Abies 

 douglasii, mendesii, and excelsa, Californian and European SiJruce, Laricc 

 or Larch Pine, Ash, and Mountain Ash. The seeds of all those mentioned 

 are cheap and easily obtainable. Cuttings of the Elm, Plane, and Poplar, 

 which grow very freely, should be planted. The Aider, Almus glutinosa, is 

 likewise of rapid growth and makes good timber, and is particularly suited 

 for wet or swampy grounds. A mixed plantation of the various trees 

 mentioned would yield a good return in twenty or twent^^-five years. 



I will now give the size and age of a few varieties of some trees in my 

 grounds near CUve. All the trees are measured two feet above the surface 

 of the ground, the seeds of all were sown by myself; dates taken from my 

 diary. 



Thuja knightii^ 30 inches in circumference, or 10 inches in diameter ; 

 about 20 feet high ; age, 3 years and 11 months. 



Cupressiis macrocarpa, 63 inches in circumference, or 21 inches in 

 diameter ; about 30 feet high ; 10 years old.
