hands and arms with pure water and then rub them well with about 

 a teaspoonful of strong ammonia water and immediately wash this off 

 in clear water after making the inspection. Also, since such spores as 

 reach the clothing must adhere rather loosely in order to be in danger 

 of carrying the disease to uninfected plants, it is believed that the 

 chances of spreading the disease on the clothing will be very small if 

 after each inspection of infected plants the clothing is brushed with 

 a wisk broom moistened with strong ammonia water. 



Naval stores operators can obtain about 30 per cent more turpentine 

 and 35 per cent more rosin than is generally obtained from trees by 

 increasing the number of chippings during the season to twice a week 

 instead of once, the streaks being cut, however, only ^ inch instead 

 of Yz inch high, the present standard, the end of the season thus show- 

 ing the faces no higher than when 3^ -inch streaks are cut once a week. 

 This method of operation has been tried by the Forest Service on a 

 tract in Mississippi. The report on the experimental work states that, 

 taking all additional expenses into account, and in the light of 1916 

 prices, double chipping should increase the net profits from a turpen- 

 tine crop of 10,000 faces by about $450, the increase from a 50-crop 

 operation yielding about $22,000. Experiments cannot, however, give 

 sufficient data to show the effect of this system upon the trees in the 

 second and subsequent years. In cases where the trees are to be cut in 

 a year or two, this method of chipping should be especially advanta- 

 geous, but indications are that it would cause a severer strain upon the 

 vitality of trees than ordinary methods. 



Western Conservationists and Pacific Loggers 



The Western Forestry and Conservation Association and the Pacific 

 Logging Congress held their annual meetings in Seattle during the week 

 of October 15. The first two days were given over to a joint meeting 

 of Federal, State, and private forest officers and timberland owners 

 for the consideration of questions pertaining to forest-fire protection, 

 the third to the Annual Forest Industry Conference, and the last three 

 days to the Pacific Logging Congress. A feature of special interest in 

 connection with the forest-fire conference was the report of the "Com- 

 mittee on Standardization," whose purpose has been to standardize the 

 business systems, forms, and reports of the various co-operating 

 organizations. Other important topics discussed included problems
