The North American Sundial Society likes to record public sundials that are in good or excellent condition. Dial #797 in Cranford, New Jersey is a sad exception. In 1972 the Kiwanis Club of Cranford presented a 15-foot diameter sundial to Union College as an expression of interest in the college and the youth of Cranford. But the years have taken a toll where it sits adjacent to the William Miller Sperry Observatory. The dais stonework mortar has given way and the concrete dial face has deteriorated.
A plan to restore the dial is underway. Dr. Stephen D. Nacco, of Union County College, Vice President, Administrative Services & Executive Assistant to the President set up a Sundial Fund under the Union County College Foundation, a 501(C ) 3 not-for-profit organization. Donations can be made online via the Web Site, http://www.uccfoundation.org/give.html with the donor selecting GIVE ONLINE NOW. Choose Donation Type "Other", and then put “Sundial” in the Additonal Comments Area as the reason for the donation.
