                                                         Exhibit (a)(5)(LL)
TO ALL WILLAMETTE SHAREHOLDERS:

                        WILLAMETTE IS "NOT FOR SALE"

               HOW MUCH WILL WILLAMETTE'S DECISION COST YOU?

Since Weyerhaeuser's first offer for Willamette in August 1998, the board
and management of Willamette have been unwilling to negotiate a transaction
that would provide a premium to Willamette shareholders. Although
Weyerhaeuser is willing to increase its offer above its current price, we
believe that the Willamette directors have made it crystal clear that the
company they have been entrusted to manage for you is not for sale at any
price.

              WE BELIEVE WILLAMETTE'S EXISTING DIRECTORS HAVE
                     NO INTENTION TO SELL AT ANY PRICE

While the Willamette board claims that it takes its fiduciary duty very
seriously, we believe the facts speak for themselves--"Willamette is not
for sale."

                ASK YOURSELF: WHAT WOULD MY SHARES BE WORTH
                         IF WEYERHAEUSER WENT AWAY?

We believe that by failing to pursue Weyerhaeuser's all-cash premium offer,
Willamette is jeopardizing the value of your investment. Even Willamette's
CEO expects "dislocation" in the price of your shares if Weyerhaeuser goes
away.

              VOTE GOLD NOW TO TAKE CONTROL OF YOUR INVESTMENT

We believe that you deserve a board of directors that will act to protect
your interests. You can make your voice heard in a manner that cannot be
ignored by your board of directors by electing the Weyerhaeuser nominees at
Willamette's June 7th Annual Meeting. If our slate is elected at the June
7th meeting and Willamette continues to refuse to negotiate, Weyerhaeuser
intends to nominate a slate of directors for election at Willamette's 2002
Annual Meeting. HOWEVER, IF THE WEYERHAEUSER NOMINEES ARE NOT ELECTED ON
JUNE 7TH, WE WILL WITHDRAW OUR OFFER, SINCE IT WILL TAKE AT LEAST TWO MORE
YEARS, UNTIL THE 2003 ANNUAL MEETING, TO EFFECT A TRANSACTION NOT APPROVED
BY THE CURRENT WILLAMETTE BOARD.
