used, are attached to the end of the main loading line. The crotch 
lines are attached to the logs by means of hooks, tongs, or slings 
(figs. 51, 61, and 62). Where more power is necessary because of the 
size of the logs, a 14 by 2 inch fall block in addition to the corner 
block is used (fig. 60). In such cases, the main loading line, gen- 
erally seven-eighths inch in diameter, passes through the corner 
block, then through the fall block, and thence to the top of the gin 
pole, where a " tail hold " is taken. 
This method followed the parbuckle method, and was very gen- 
erally used. The last three or four years it has been giving way

to overhead loading methods. It requires landings (of the type 
shown in fig. 60), which is its most objectionable feature. Landings 
adapted for this method must be made small because of their cost, 
and so afford insufficient storage space. This method is not so fast as 
overhead methods, neither does it allow the loaders the privilege at 
all times of deciding the order in which the logs shall be loaded. 
The fixed investment in equipment at one side with this method, 
where the power is furnished by a separate loading engine and no 
fall block is used, amounts to about $2,718, as follows: 
1 7 by 10 inch double-drum loading engine $1, 625 
1 set of guy lines 100 
1 main loading line 85 
1 spotting line 45 
3 14 by 2 inch loading blocks 63 
Loading-engine repair parts and materials 75 
Loading-engine sled 250 
Oil-burner equipment, including oil and water tank 375 
Miscellaneous equipment 100
