Thus when the authors discuss the decline of intercity passenger service, they relate specific events to the increased use of private automobiles, the expansion of bus service (the GN, in fact, promoted the early Greyhound system, largely to relieve the railroad of unprofitable branchline passenger trains), and the development of commercial air travel.

When targeting swordfish, longlines are set overnight at shallow depths (10-100 m), and a light stick is often attached several meters above the hook on every second or third branchline. In contrast, when tuna are targeted, longlines are set at dawn and hauled in at late afternoon or evening.
