A series of tables shows costs of skidding as determined by various types of equipment, distances for skidding, percent of slope, logs per MBF, and MBF per acre. By consulting these tables a contractor can compare methods of skidding according to their relative operating costs and thus estimates must be regarded as tentative and subject to revision.

Costs of skidding with 25- to 80-drawbar hp. crawler tractors in southwestern Montana are analyzed and compared. Data include operating times, terrain classes, steepness of slopes, efficiency of operators, costs of owning and operating, and log production. Charts enable a user to quickly estimate skidding cost per MBF considering distance from log deck to log-making area, type of terrain, average slope, and efficiency of operator.

S2Because of the great and growing interest in outdoor recreation, many studies are being made by private and public agencies that need information for planning use of land and facilities for recreational purposes. In these studies much attention is being given to the people who use recreational facilitieswho they are; where they come from; what they like; what they want; how much they are willing to spend. Many types of surveys are being used in studying these people. The main question in planning a survey of this sort is: What survey technique can be used that will provide the most reliable and valid results at the least cost? To get an answer that we could use in our recreation research program, we made a study of four different survey techniquesa personal interview, a handout questionnaire, an immediate mail questionnaire, and a delayed mail questionnaire. Results show that the delayed mail survey, conducted 3 months after the camping experience, gets the best results at the least cost. Our study is described here for the benefit of other research workers in outdoor recreation.S3.
