[Later that day, the same sheaf of papers are rather inelegantly (but carefully) shoved back under Hiccup's own door, still in the same order as they were left, but curiously, with two new pieces of paper torn carefully from a Breeder's notebook inserted into the middle.
The first is an equally painstakingly drawn schematic, annotated and supplemented with a list of materials and quantities inscribed in one of the margins; the other is a scrap of paper with "runes" of a slightly different variety sketched quickly onto it, with two lines of symbols printed clearly beneath.
Should Hiccup take the time to decode those two lines of symbols with the help of that sketch, he may discover that they read:
DA VINCI KNEW TO WRITE HIS NOTES IN CODE, KID. THIS ONE IS CALLED PIGPEN. MIGHT AS WELL KEEP THINGS IN THE BARNYARD.
