James Craig McLanahan teamed up with partners to buy a foundry in Gaysport, Pa., in 1835. That venture eventually became McLanahan Corp. Samuel Calvin McLanahan invented processing equipment that changed the industry, such as the log washer and single-roll crusher. McLanahan Corp still thrives today in Hollidays- burg, Pa. Infrastructure One of the biggest issues facing ev- eryone in the rock products industry was the need to develop infrastruc- ture within cities. The increased con- struction of sidewalks in urban areas was gaining much attention. At a con- ference in St. Louis, the focus was on funding blue-colored sidewalks not covered in the city ordinance. The contractor argued successfully that the blue tint saved "thousands of eyes annually, while it does impair the good quality of the work." Another issue facing cement and con- crete manufacturers was the rapid development of waterways and sew- er systems. In 1896, Chicago con- templated substituting concrete for brick in the sewage system in order to escape the escalating cost of brick at that time. Brick workers quickly smothered the idea, though, and the editor commented that, "the cement interest is too much scattered to effect positive legislation in their own inter- est." He went on to urge crushed stone producers, who were "well equipped, with brains and energy to conserve their own interest," to help rally on be- half of concrete sewer pipes. While production figures in 1896 were low, by 1901 cement production had in- creased by 800 percent to 12,711,225 bbls, or 2.4 million tons. And while 1897 to 1900 saw imports yearly of about 2 million bbls, 1901 imports only reached 940,000 bbls, a direct result of the burgeoning U.S. cement industry. Estimated value of stone production in 1901 was $61 million. The rock products industry was in its toddler years, and wide-eyed and ready for the challenges to come. The same issues producers faced during the early years of Cement & Engineer- ing News would continue to loom ever larger, as city populations threatened to outgrow transportation systems and housing, and sanitary and safety issues began to move to the front. Serve the Trade April 1902 saw the first issue of Rock Products, published in Louisville, Ky., by E.H. Defebaugh. The mission state- ment stated, among other things, that the magazine would "serve the trade in every honorable way possible, and to do it so persistently and thoroughly as to not only merit the support of the trade, but get it. We know there are al-
