Get your bearings.

Stay on course:

Get Cutless bearings.

Made only by BFGoodrich.

There are lots of water-lubricated shaft bearings.

But the only one that's earned the right to be called Cutless is made by BFGoodrich.

In fact, that good old water-lubricated Cutless bearing is better than ever. Its exclusive "Water

Wedge" channels, molded from a tough, specially- formulated BFGoodrich resilient rubber, wash away dirt and abrasive particles. And any water- fresh, salt, even sand-filled—will lubricate the

Cutless bearing.

You H find Cutless bearings in yards and marine stores around the world. In a full range of shaft diameters and lead capacities.

So uphold a seagoing tradition: set your course for Cutless bearings. Only from BFGoodrich.

Annual Net Income Of

McLean Industries Rose 132 Percent For 1984

United States Lines' parent com- pany, McLean Industries, has re- ported 1984 net income of $61,564,000 on revenues of $959 mil- lion, compared with the previous year's net of $26,552,000 on reve- nues of $784.5 million.

The parent firm's president,

Malcom P. McLean, attributed the 132-percent rise in net income to "continuing improvements in the efficiency of our transportation sys- tem." The 22-percent growth in rev- enues, he said, was the result of new ships being placed in service and continuing growth in cargo vol- umes.
