some question about intended endings guide

[saiyangoku]

When I see the intended endings guide, I have found some questions.

In the first part of "intend ending guide", the website note that:

"In his chapter comments for chapter 249, which appeared in the 49th issue of Shueisha’s “Weekly Shōnen Jump” in 1989 (and was later recorded in Daizenshuu 7), Toriyama likewise noted:
Dragon Ball, which I planned on lasting one year when I started, has now been in serialization so long that it’s surpassed Dr. Slump! I feel both happy and scared… "

I have Daizenshuu 7 , but can not find out this chapter comment.

Can anyone tell me which page this comment locate ?

That quote of Toriyama's can be found on page 311 of Daizenshuu 7.
