A Miracle in Modern Seership

I've seen this mentioned in an ad before, but I am still having the hardest time figuring out what it actually is. The ad mentions an apparatus, but the closest explanation I could find about this trick was in this scanned pdf of a typed copy of Burling Hull's dictionary of Mentalism, and after reading through the trick, it would appear that the only thing you need apparatus-wise is a short pencil and a small, thicker stock sheet of paper.

How great is the little devil in the upper corner?!
This is the first time I have come across the name "Burling Hull," and to be honest, I thought it was some kind of brand or address. MagicNook.com set me straight. Apparently Hull is a person- the self-proclaimed "Edison of Magic"- he created dozens of magic tricks (and held the patent on the Svengali Deck) and wrote over 50 books!

I did find this quite from Magic Nook to be very telling:

Although an important figure in magic, his often outrageous claims and many empty promises led him to be widely known as 'Hurling Bull'.

He was quite an interesting character- he even wrote an entire book just to defame a rival magician (see the wiki for more)! Mr. Hull lived to the age of 93, and if you would like to know more about him there is a biography which was published in 1977 called The Edison of Magic and His Incredible Creations.
