SELLING WOODLOT PRODUCTS ON MICHIGAN FARMS. 



pounds. Less than carload lots can, of course, be shipped, but at a greater 

 expense per 100 pounds. When one farmer has less than a carload to 

 sell, two or more may combine in order to take advantage of the lower 

 rate. Freight rates over two or more lines are higher than when the 

 same distance is covered by only one railroad. Such comljined rates 

 can be worked out and other information secured on inquiry of freight 

 agents. The approximate weights per 1000 board feet of lumber and 

 logs, and per cord of bolts, for different species of trees are shown in 

 table 8. Table 9 gives the weight per stack of green and air-dry bolts 

 of different species and different lengths. The advantage of shipping 

 air-dried material is at once apparent. Not all the native species are 

 given in the table, but their weight may be quite closely estimated by 

 comparison with some of the others. For instance, the weight of aspen 

 would be about the same as that of cottonwood, that of soft maple 

 about the same as that of cherry, etc. The figures in these tables are not 

 given as weights adopted by any railroad company, but only as average 

 weights upon which the timber owner may base his preliminary estimates 

 of the cost of shipping.
