The Fourth Annual Report of the Forest Park Reservation 

 Committee of New Jersey for the year ending October 31, 1908, 

 contains, besides, the report of the committee, one by the state 

 forester, Alfred Gaskill, and another from the forest fire service. 

 The longer articles are by Mr. Gaskill on the planting and care 

 of shade trees, by John B. Smith on the insects injurious to shade 

 trees, and by Byron D. Halsted on the fungi of native and shade 

 trees. The topics included contain such varied ones as the 

 progress of forestry in New Jersey, state reserves, types of forest 

 fires, methods of extinguishing and of controlling forest fires, 

 shade trees, roadside trees, seashore trees, New Jersey tree nur- 

 series, how to plant trees, tree guards, pruning, tree diseases, 

 sprays and methods of spraying, and injuries due to soil condi- 

 tions. The forty-odd illustrations are numerous, clear, and 

 varied ; each has a definite value and adds materially to the use- 

 fulness of the report. Several of the best have appeared in ear- 

 lier state reports or botanical publications ; mention might be 

 made of the helpful figure on page 68 showing how to plant a 

 street tree. To this readable report are appended the various 

 laws affecting state and municipal parks, forests, the forest fire 

 service, and tree planting. The report is designedly non-tech- 

 nical, apparently ; it is a most readable account of what the state 

 has done and is doing, and should interest the people of New 

 Jersey in the greater improvement of public and private forest 

 land.

 Rubber Situation." Aside from stating in a general way, the 

 factory processes in the manufacture of crude guayule rubber 

 and the extent and future of the industry, the author gives an 

 account of the early extraction of rubber from the plant by chew- 

 ing. He tells of the discovery of the plant {Partlienium argenta- 

 tum) to botanical science in 1852, and in giving a description of
