of this method. A fiber-board carton was then selected which could 
be sealed, or in which had been placed an inner seal, to prevent the 
entrance of insects. Such a package to be successful should stand 
the same shipping conditions as a wooden box and should not, when 
sealed, greatly exceed the latter in cost. A carton of the following 
specifications was tested to determine its shipping qualities:

SHIPPING TESTS OF FIBER-BOARD PACKAGES. 
Three 25-pound boxes (Pl. III) made according to the foregoing 
specifications were filled with 25 pounds of dried peaches, sealed, and 
given the following shipping tests: 
Box No. 1 was shipped by express from Sacramento, Cal., to Port- 
land, Me., and back, or about 6,000 miles, durmg which trip it was 
handled by at least 18 men. This box arrived in Sacramento in good 
condition and is shown in Plate III, figure 3. 
Box No. 2 was shipped from Sacramento, Cal., to Fargo, N. Dak., 
as one of the bottom boxes in a car of 25-pound boxes of dried fruit. 
Except for one place where the sharp edge of a wooden box had worked 
up the edge, this box arrived at its destination in fine condition, as 
illustrated in Plate III, figure 3. This rubbing would not occur in a 
carload of fiber-board boxes. 
Box No. 3 was sent to San Francisco by Parcels Post, where it was 
trucked around the wharves, given a thorough test, and examined 
by several packers and by the agent of one steamship company. It 
arrived in Sacramento in good condition, after having stood the test 
and having been pronounced a good shippmg package for dried 
frome: “(el EE tio 3.) 
The foregoing tests proved that the 25-pound package of dried fruit 
could be shipped long distances, and its shipping qualities compared 
very well with the wooden box. 
These fiber-board boxes (Pl. IIT) weigh much less than the wooden 
box, and the saving on the freight would be considerable. In the 
case of the 25-pound box the saving per car on the basis of $1.10 
per 100 (freight rate) is about $23. It was estimated that the adop- 
tion of this style of package would save one company approximately 
$40,000 annually.
