McKeesport, and furnished with up-to-date machinery and 
equipment. In September, 1904, the company moved to 
these premises which were occupied until 1911. This period 
was a very eventful one in the history of the firm. It was then 
that they introduced their famous package of food confection, 
—Zig Zag—which became immensely popular to the extent 
of national distribution. The D. L. Clark Company was the 
originator of this type of confection in this district and its 
popularity has never waned but rather has increased from 
year to year. 
In 1911 the property and equipment of a bakery and con- 
fectionery factory on the North Side, Pittsburgh, marking 
part of the present site, was purchased, and the company 
moved back to the district where their modest start was made 
twenty-four years previous. 
The above year also marked the introduction of another 
famous Clark product to the public. After years of experi- 
menting Teaberry Gum was pronounced ready to uphold the 
Clark reputation for quality confections and was accordingly 
placed on the market. The sale of this product reached such 
proportions that, owing in great measure to the extreme 
variation in marketing procedure between Chewing Gum and 
Candy, the Teaberry Gum department was transferred in 
April, 1924, to The Clark Bros. Chewing Gum Company. 
This company was organized for the purpose of marketing 
and manufacturing Teaberry Gum and immediately com- 
menced operations in a splendidly equipped factory, modern 
in every respect, and located adjacent to The D. L. Clark 
Company factory. D. L. Clark is also President of the new 
company. 
At regular intervals other famous confections now ap- 
peared to take their places in public favor along with Zig 
Zag and Teaberry Gum. Undoubtedly the most popular of 
these has been the Clark Bar,—the biggest nickel’s worth of 
quality candy in the country today. The quality of this piece 
of candy is such that the firm did not hesitate to place its 
stamp of approval by giving the bar its name,—and the 
public by buying it in such quantities that a sale of two 
hundred million bars is predicted for 1925. Red Cap Suckers,
