planting of about half this lot had to 

 be postponed, and the holes dag over 

 again. 



To offset to a certain extent the cost 

 of the three-acre lot, I thought it would 

 be as well to try some quick growing 

 crop that would not take up too 

 much room, and would to as small an 

 extent as possible retard the growth 

 of the trees. I selected California pota- 

 toes, and treated the seed to a bath of 

 sulphate of copper, to see if that would 

 prevent the rot that is so prevalent in 

 Kula. 



Last July, notwithstanding the rot 

 that did attack them, and the exception- 

 ally dry weather that we have had all 

 this year, I took off a crop of potatoes 

 that netted me 80919. This amount, 

 deducted from the cost, $1 16-90, left §7771 

 or say §25*90 per acre for the three-acre 

 piece, as against sfl8-40 for the unculti- 

 vated acre. 



One year from planting the trees the 

 following measurements were made : — 



The tallest tree in the uncultivated 

 lot was 5 feet 3 inches, a Eucalyptus 

 Botryoides, and the average height of 

 the whole of that piece was 3 feet. 



In the cultivated lot the tallest tree 

 measured 16 feet, Euc. Rudis, the other 

 tall ones being : Euc. Botryoides, 15 

 feet; Euc Corynocalyx, 12 feet; Euc. 

 Leucoxylon, 12 feet; Euc. Paniculata, 

 12 feet; Euc. Corymbosa, 6 feet. 



Tbe best average height, and the 

 evenest grown lot of trees was the 

 Euc. Botryoides ; the poorest being the 

 E. Corymbosa. The average height of 

 the whole three-acre lot was over 10 

 feet. One stray (Blue gum) Euc. 

 Globulus, that was accidentally plauted 

 in the cultivated lot measured 12 feet in 

 height. This tree had exactly the same 

 treatment the others had, which goes to 

 show pretty well, that both Rudis and 

 Botryoides are faster growers than the 

 Globulus ; both these species are ranked 

 very highly in Australia for railroad 

 ties and fence pests. This is well to be 

 known, especially as the Globulus, or 

 Blue Gum, is the Eucalyptus most 

 commonly grown at the islands, and 

 except for firewood, is the poorest for 

 any purpose. 



Results. 



Considering the unusually dry weather 

 we have had for the last twelve months, 

 I consider the growth of the trees in the 

 cultivated lot remarkable. 



Under normal conditions, that is, where 

 there is not a heavy growth of manienie 

 to contend with, the cultivation of the 

 trees should cost very much less than 

 the amount above shown. 



542 [June, 1909- 



The difference in favour of the culti- 

 vated as against the uncultivated trees 

 is so great in favour of the former, that I 

 shall favour the cultivation of all trees 

 hereafter planted on the ranch, wherever 

 the location is such as to make it 

 possible. 



As showing what the possibilities are 

 of fence post production, I would call 

 attention to figures heretofore reported, 

 viz., that last year I cut 244 good fence 

 posts, five to twelve inches in diameter, 

 from 38 second growth Eucalyptus 

 Rostrata trees, twelve years old. Some 

 of these posts have been put in the 

 ground plain and the balance subjected 

 to Creosote treatment by the Kahului 

 Railroad Company. All of these posts 

 will have the date stamped on them, and 

 the place of use recorded in the ranch 

 forestry book; so that their respective 

 life in the ground can be ascertained 

 accurately. 



The foregoing results, I submit, are 

 such as to more than warrant all plant- 

 ations, especially those which use rail- 

 roads and have large amounts of fencing 

 to do, experimenting with cultivated 

 forestry. 



General Re-foresting for Conser- 

 vation Purposes. 



This subject, like the poor, is always 

 with us. What has been said and 

 repeatedly re-said on this subject is 

 to-day more vital to the agricultural 

 interests of Hawaii than ever, and in no 

 case more so than to the irrigated sugar 

 plantations. 



On every island forestry reserves have 

 been set apart on paper, but scarce any- 

 where has there been anything but the 

 most limited attempt at re-foresting. 



Under normal conditions, protection 

 from live stock would be sufficient, as 

 the forests would reseed themselves. 



For several reasons this does not take 

 place in most locations in Hawaii. The 

 multitudinous insects which devour the 

 forests and a root fungus which is 

 killing the natural woods by thousands 

 of acres in a number of localities and 

 the heavy growth of the Hilo grass and 

 other coarse grasses which so cover the 

 ground that seeds cannot germinate, are 

 rapidly destroying forests in regions 

 where water conservation is most 

 needed. 



Whether or not the entomologist can 

 introduce parasites which will neutralize 

 the deadly effect on forests of iusects 

 and fungus growths is now being made 

 a subject of study by the Planters' 

 Experiment Station. It will probably 

 be far more difficult to obtain results 

 than it has been to meet the ravages of
