number of cases is indefinite, the si rips may bo. laid under the desired 

 row on the next to top layer, in which circumstance old ease lids 

 should be nailed from strip to strip, here and (here, to insure their 

 remaining parallel (fig. 5).. 



A strip the entire width of the car is available when the end form 

 of stowing is used in placing a step-joint, 

 load, and also when the load is of the straight- 

 joint type. If the step load, placed from the 

 side, is to be braced, the same principle may be 

 employed by cutting 2 by 4's into 11-inch 

 lengths (fig. 5), fastening them together with 

 old case lids, and putting one such brace under 

 every other case on the row in front of that to be held in place 

 (fig. 1). It will readily be seen that these lateral braces under the 

 ends of the cases lend themselves to a great variety of puzzling situa- 

 tions. A few of the most usual ways in which they have been found 

 useful are shown in figures 1, 3, and 6, and Plate III. These illus- 

 trations show cars stowed with straight- and broken-joint loads, in 

 which the lateral braces under cases were used. If the method of 

 side loading is used, the incomplete layer will extend the length, 

 rather than the width, of the car. In this case the short braces, 



spaced by pieces of 

 old case lids, as in 

 the step-joint load 

 (fig. 1 and PI. Ill), 

 are used. 



THE RAILROAD HAUL. 



It has been difficult 

 to devise a method 

 of recording the 

 shocks incident to 

 ordinary freight - 

 train running and 

 handling as felt in 

 the carload of eggs. 

 Several instruments termed " impactographs " have been devised, 

 and these have been used in the egg car itself, as well as in the 

 caboose w T hich the investigators occupied, in accompanying the car- 

 load of eggs under observation from origin to destination. A num- 

 ber of records, having the same general character as those shown in 

 43010°— Bull. 664—18 2 



Fig. G. — Lateral braces under cases in a straight-joint 

 load. Layer 4, stack 3, contains only 4 cases. When 

 such incomplete stacks are to be braced, the strips un- 

 der the cases must be in at least 2 sections.
