This article describes the discovery of a unique sundial carved into the base of a former churchyard cross at Barcheston, Warwickshire. The stonework was trimmed to a 52° slope on the south side, with recessed flat regions revealing traces of hour lines. It is classified as a large horizontal in stone with a notably wide gnomon.

Tony Wood writes about a porcelain dial from 1766 at the Royal Worcester Porcelain Museum, describing its detailed delineation. Jill Wilson responds to Chris Williams' mass dial article, noting a correlation between dial distribution and geology, and suggesting further research into building materials and church histories for a complete picture of dial loss.

Jill Wilson provides further thoughts regarding Chris Williams' mass dial article, suggesting that areas with low numbers of recorded mass dials might be poor in suitable stone. She emphasizes the need for a full record of churches surveyed, including those without extant mass dials, highlighting the challenges for mass dial researchers.

Jill Wilson reports on a successful weekend course on 'Understanding Sundials' at Farncombe Estate. The curriculum covered the history of dialling, fundamental theory, design principles, practical delineation using various tools, and the practicalities of installing dials, with a focus on wall declinations. Attendees, from beginners to experienced diallists, gained new insights and appreciation for sundials.

This review covers Tony Moss's PowerPoint CD-ROM "Sundial Presentations," which includes "Concepts for Students of Sundialling" and "Using and Understanding Sundials." It praises the CD for its clear, animated slides explaining basic sundial concepts, theory, alignment of gnomons, differences between clock and sun time, and the analemma, making it useful for beginners and lecturers.
