In the next decade, Jordan's health began to decline, and he sold his half of the company to Henry Cowell in 1865. With the firm renamed Davis and Cowell, Henry Cowell and his family moved to Santa Cruz, where he took over Jordan's former duties. After Davis died in 1888, Cowell acquired full ownership of the company, and it became Henry Cowell and Co. Operations and land acquisitions continued to expand over the next twenty years; encompassing expanded lime production, cattle and milk cows, bituminous rock mining, tan oak bark (used in leather tanning), grain and fruit. In 1898, the company incorporated as the Henry Cowell Lime and Cement Company. The transition to Portland cement, which could be used to manufacture mortar superior to lime-based mortar, began the decline of the lime industry after the start of the 20th century. Henry Cowell's son Harry finally shut down the Bay Street kilns in about 1920.
