Tree Measurements at San Jorge, Uruguay. 4o7 



is, that their results seemed to me uncertain and unsatis- 

 factory. 



In January 1887 I added a twenty-ninth tree to the list — 

 an ombri {Phytolacca clioica) ; but as this was a year or two 

 after subjected to rough usage, horses being tied up under 

 its shade and cattle and sheep rubbing against it, its growth 

 cannot be said to be normal, and I do not include this grand 

 vegetable among my tables of tree-measurements. And in 

 December 1889, partly in \new of my own projected absence 

 from San Jorge, and not wishing to tax more heavily than 

 necessary the time and energies of my sufficiently-busy 

 manager, who now continues the tree-measuring work, I 

 struck out of the list a fig, a walnut, and a Spanish chestnut 

 tree, all doing well, but growing very slowly ; also a silver 

 poplar, which grows in ground habitually dug over once or 

 twice a year, but, though healthy, this tree grows very slowly. 

 I also omitted a Eobinia and a Blackwood, likewise planted 

 in land forked over about once a year. I also turned out a 

 " cina-cina " (ParkiTisonia) and an acer (species ?), a very poor 

 specimen, whose measurement rendered the record of its 

 species highly deceptive. I have ouly seven or eight grown 

 plants of this tree, but all greatly exceed in growth this one 

 of two specimens I chose for measuring purposes. 



I now measure twenty trees, as follows : — 



1. You7ig Trees. 



Evergreens. — Two Acacia mollissima (or ? Acacia dealbata). 

 Two Eucalypti, common varieties ; but not E. globulus 



(blue gum). 

 Two Stone pines {Pinus pinea). 

 Two Black woods (Acacia melanoxylon). 



All these grow on undisturbed grass, and in enclosed 

 ground. 



Deciduous. — Two oaks from English acorns, but I do not 

 know if Q. Eohur or not. These are in gi'ound 

 forked over yearly. 

 Two Paraisos {Melia azcdarach). 

 Two Lombardy poplars {Populus fastigiata). 

 Two Eobinias (Eobinia 2Jseudoacacia).
