Granger has a street in Howick named after him. In 1878 the brickworks was sold and Granger bought the equipment and set up a large brickworks at the head of the Whitford Creek in Whitford. They also ran a lime factory based on crushing and burning shells at Eastern Beach. Shells lay in beds several metres thick on the flats which extend 400 m inland from the beach. The factory was built on a concrete base about 20 metres by 15 metres by 1.4 metres thick on the seaward side on the waterfront, 30 m south of the intersection by the restaurant. The site is now marked by a short wooden walkway under the phoenix palm trees. The shells were burnt for 3 days at a temperature of about 800 °C to turn the solid shells into lime when it was mixed with fresh water. The three kilns were beehive-shaped, about 1.8 m high. Alongside the factory, a long wooden jetty went 10 metres out to deeper water. A flat-bottomed sailing scow was bought in on the high tide, loaded, then floated off on the next high tide. The shell was brought to the kilns on a miniature railway. One of the early workers at the lime works was Alexander Shaw, who had migrated from Ireland and initially worked at the Coromandel gold fields. Alexander later worked at Granger's bricks works when it moved to Turanga (Whitford). Workers came from Howick, walking around the Mellons Bay cliff base when the tide allowed. About 50 m west of the beach are some noticeable depressions in the shell soil near no 19, where many hundreds of tonnes of shells were removed. The lime produced was used for mortar, lime render and for tanning leather.
