about 30 per cent of them can be used again without re- 

 pair. At the end of each trip, at least one door is cut to 

 pieces to release the grain. This one is practically entirely 

 wasted. The ends of many of them are battered so badly in 

 taking them out that they need much repair. This means a 

 very large waste of lumber annually. 



A new grain door has been designed and patented, called 

 the McNulty grain car door, which promises to do away with 

 much of the timber wasted in the present consumption of 

 doors. Its best merits are founded on two facts, viz.: That 

 it is not nailed solid to the door posts of the car but is hooked 

 and can be easily released, and that it has a sliding door in 

 itself through which the grain can be run out, instead of cut- 

 ting the door to pieces. These doors are built in two widths 

 and two lengths, viz.: Six and seven feet long, to fit cars of 

 different sizes, and 20 and 24 inches in height, the 24-inch 

 door being used at the bottom and contains the slide to release 

 the grain. These are well constructed, being made from 

 No. 1 Douglas fir grove and tongue material, 1% inches thick 

 with ship lap joints. This makes a door tighter and also 

 tronger than the door now most generally used. To further 

 insure a tight fit in the car, a strip of coarse paper is placed 

 between the door post and this door. 



Instead of being nailed to the door posts, as are other doors, 

 this one is held in place by one hook on each side, which 

 drives into the door post. The hooks on all doors are at the 

 same height and the same length, so the same hole in the 

 post can be used several times. The hooks are on a sliding 

 arrangement so they can be used on cars of any width door. 

 The advantage of the hook arrangement is in the time saved 

 in placing the door in or taking out of cars, door post of car 

 is not strained as much, and most important of all, doors are 

 not split up by nailing in or by removing from cars. 



The original cost is said to be only about twice that of the 

 common door used, and it is maintained that one will last 

 indefinitely, although up to date, no door has been traced over 

 about 30 trips. The success of this door will mean a saving 

 of several million feet of timber yearly, saying nothing of 

 time and convenience.
