Prior to the construction of a causeway in 1968, the Petitcodiac River had one of the world's largest tidal bores, which ranged from 1 to 2 metres (3.3–6.6 ft) in height and moved at speeds of 5 to 13 kilometres per hour (3.1–8.1 mph). With the opening of the causeway gates in April 2010, the river is flushing itself of ocean silts, and the bore is returning to its former size.

Fish-Scale Tides

On 31 July 2022, an unusual tidal phenomenon, a fish-scale tide, took place on the Qiantang River's estuary in Zhejiang Province, China. I've not found any explanations for it thus far, so I'm assembling my own. (Image credit: VCG; submitted by Antony B.)

Wood Engraving Wednesday

HARRY BROCKWAY & SARAH VAN NIEKERK

British wood engraver Harry Brockway (b. 1958) pays homage to one of his major influences, English wood engraver Sarah Van Niekerk (1934-2018) in 2020 Vision: Nineteen Wood Engravers, One Collector, and the Artists Who Inspired Them, printed in 2020 by Patrick Randle’s Nomad Letterpress at the Whittington Press in Cheltenham, Gloucestershire, in an edition of 340 copies for the 100th anniversary of the Society of Wood Engravers.

In his presentation, Brockway has a block by Van Niekerk reprinted, Severn Bore (top), and then engraves a self-portrait of himself printing Van Niekerk’s block, which he titles Printing Severn Bore (below). Van Niekerk’s block was loaned for this printing by Jess Van Niekerk and Brockway produced his engraving for this publication. Of Brockway’s relationship to Van Niekerk and to this particular print, Brockway writes:

I first met Sarah at the Royal Academy in the autumn of 1981. Sarah had taken over as tutor of wood engraving from her mentor Gertrude Hermes some five years previously. . . . I nervously ventured into the print department and was immediately presented with a block and a few tools and left to get on with it. Sarah’s teaching technique was quite subtle. I cannot remember being told how it should be done beyond a basic demonstration of how to hold the tools. She had a quite manner and an air of authority. She . . . taught mainly by allowing me to work alongside her as she worked on her own block. I now realise what a privilege this one-to-one tuition was. . . .

After Sarah died in June 2018 I acquired the press that she must have used to print Severn Bore. She lived in a house on the banks of the Severn and witnessed the Bore coming up the river “with the roar of a train.” Before she died Sarah had asked me to take some prints from the block as she was struggling to pull the handle of the press across. It is a demanding block to print with her characteristic cleared spaces and areas of black combined with delicate tones and swirling fine lines.

In my engraving I imagine printing Severn Bore on Sarah’s beloved Hopkinson & Cope press.

A day trip last summer to the Maitland area, Nova Scotia. You can see people riding the tidal bore out there! Really missing weather like this right now.

Surprise vacation, one for the locals

Hey friends, announcement time!

I’ve been able to post comics five days a week for over a year now, and it’s been an absolute pleasure. However, starting this week, I’ll be going back to a three day a week schedule: Mondays, Wednesdays and Fridays. It’s all good - I have a solo art show in August and I’m busy finishing up pieces for that, as well as co-curating and participating in a group show this fall. I also have this darn day job (as The New Yorker hasn’t discovered me yet) and family and, well, I do like my eight hours sleep each night. Hope y'all understand.

Feel free to follow my other art pursuits at www.jenzelart.tumblr.com, on Twitter at @diarysquirrel and Instagram at @diaryofasquirrel.

And, as always, if you’re reading this, I thank you for your patronage!

the photo was taken about 40km up the Petitcodiac river (seen in the distance) from the Bay of Fundy… the rivulets will fill with water as the famous high tides of Fundy cause a tidal bore that will fill the brown banks to the brim
