The giant of the rain forests is Alerce or Lahuen {Fitzroya pata- 

 gonica). This species has a maximum height of 55 meters and diam- 

 eters up to 5 meters. The trees that reach a height of 40 meters are 

 Muermo or Ulmo {Eucryphia condifolia) and Coihue {Notliofagus 

 domheyi). Those that reach a height of between 20 and 30 meters are 

 Nothofagus nitida, Huahuan {Laurelia serrata). Canelo or Foihue 

 (Drimys zvinteri), Tique {Aextoxicum punctatum) , Patagua {Myrceu- 

 genia planiceps), Luma (Myrtus luma), the two manius {Podocarpns 

 nicbigena and Saxegothea conspicua) and Cipres {Libocedrus tetra- 

 gona). 



On the east side of the mountains there are three distinct types — 

 the Librocedrus chilensis forest, the Nothofagus pumilo forest and the 

 Nothofagus antarctica forest. In both forest regions there is a full 

 discussion of all the associations found in them. 



The rest of the volume is devoted mainly to an enumeration of the 

 plants of the region, in which some new species are described. In this 

 enumeration full notes on the distribution of the species and the plant 

 associations in which each one occurs are given. The publication is 

 beautifully illustrated with 23 plates, most of which contain two or 

 more views.

Neiv Jersey Department of Conservation and Development, Annual 

 Report for ipip. 



This report, rather belated, covers only eight months — the period 

 between November 1, 1917, and June 30, 1918 — owing to the change 

 of the fiscal year for the State. Besides the general report of the 

 board, written by the director, Mr. Gaskill, it contains reports of the 

 State Geologist, the State Forester (the same person as the director) 

 and the State Fire Warden. It does not record any notable accom- 

 plishment in forestry lines but repeats the attitude taken in the report 

 of the previous year that New Jersey has too much forest : "We need 

 fewer but better forests," and that "it is far wiser to leave most of our 

 forests in private control and to make it worth while for the owner to 

 care and develop them." This is good democratic doctrine but poor 

 economic theory, and it would require some reasoning as to why it is 

 "ultimately advisable" for the State to own 40,000 acres of forest, 

 adding some 30,000 acres to the presefit acreage of State Forest. When 

 it is stated that "New Jersey can well afford to clear three-quarters of 

 a million acres of forest land" and "would then have remaining the
