text_A: The development of Guildford (to the west) was stimulated by the construction of the Wey Navigation in the 1650s. In contrast, although several schemes were proposed to make the Mole navigable, they stayed only as proposals and transport links to Dorking remained poor. As a result, the local economy began to suffer and the town declined through the late 17th and early 18th centuries.
text_B: After the proposals to improve the Mole were presented, is it likely that traders in the area purchased more expensive homes?
NO.
