In the eternal life shall we not have friends forevermore? I used to think that friendship meant happiness: I have learned that it means discipline. Seek how we may, we shall never find a friend without faults, imperfections, traits and ways that vex, grieve or annoy us. Strive as we will, we our selves can never fully fulfill the ideal of us that is in our friend's mind: we inevitably come short of it. Yet let us not give U!J friendship, though we have found this true. To have a friend is to have a solemn and tender education of. soul from day to day. A friend gives us confidence for life. A friend makes us outdo ourselves. A friend remembers us when we have forgotten ourselves, or neglected ourselves; he takes loving heed of our health, our worlc, our aims, our plans. A friend may praise us, aiul we are not embarrassed; he may rebuke us, aiul we are not angered. If he be silent, we understaiul. It takes a great soul to be a true friend - a larse, catholic, steadfast aiul loving spirit. One must forgi";e much, forget much, forbear much. It costs to he a friend, or to have a friend: there is nothing else in life, except motherhood, that costs so much. 11 not only costs time, ajjection, strength, patience, love,-sometimes a man must even lay down his life for his friends. There is no true friendship withou: self-abnegation, self-sacrifice. Let us be slow to make friends, but, having once made them, let us pray that neither life nor death, misunderstanding, distance nor doubt may ever come between us, let us be self-possessed in friendship. There are so many ways of grieving a friend,-shall we not walk softly before him? Let us be true to friends, and then believe that they are aiul ever will be true to us. True love never nags it trusts. One of the dearest thoughts to me is this,-that a real friend will nei•er get away from me, or try to. Love does not have to be tethered, either in time or eternity. -ANNA R. BROWN LINDSAY in "What Is Worth While?"

Our forests constitute one of the greatest natural treasures of our nation, a treasure we can translate into economic benefits for our people. Among others, they help provide food, fuel and shelter for our people. For this reason, I appeal to our people to take the steps necessary for conserving this treasae of ours in order that we and those to come after us will always be able to avail of the blessings offered by our forests. tQ(I I ., j ""~ --/ @ffice of t~e Jiu freaihent of tip Jltflippi118 Jftal•n&itaits I convey greetings to the alumni and student body of the U.

I would, therefore, avail myself of this opportunity to inject a sense of urgency into the minds of those who have passed through the portals of the U. P. College of Forestry, as well as those who are still within its halls. They have a mission. The}- have a task - the conservati'on of this country's patrimony, the preservation of the vast wealth of fts forests. ~ hl L.AK u .c.L l'.c.

It is indeed a timely venture at this ti•• vhen a lot of our petty farmers destroy acre• of forest to en hance their , unacientific ways. Poreat conserva tion in our country would likely be encouraged thru uaeful information diaaeminated to our people by this medium of comaunication. It ia noteworthy also that more and more of our youth are getting interested in this field of endeaTor if only to preser Te major source of our groas national income necesaary to stabilize our economy.

UNIVERSITY OF THE PHILIPPINES QuEzoN CrrY OFFICE OF THE PRESIDENT MESSAGE It is a pleasure to greet the staff and readers of Forestry Leaves on the occasion of Arbor Week. The occasion should recall the pertinence of the proper means of guaranteeing the natural resources of the nation through scJ.entific techniques and attitudes. The wealth of the nation needs conservation, development, and exploitation; and these tasks are for all generations to assume since we must maintain the national independence through economic strength that is both progressive and consistent. Consequently, we need a vehicle that could disseminate valid attitudes towards our national wealth, in this particular instance, the national wealth that is to be derived from the reserve, as it were, of our natural resources. It is a happy fact that the College of Forestry, University of the Philippines, has precisely this vehicle in the Forestry Leaves. Its mission is to continue to function as a medium of thoughtful discussion of the proper means of increasing our national wealth. As tar as I remember, Arbor Week which used to be ob served only tor one day has been celebrated since I was a little boy. And I do not recall any single celeoration which is worthwhile reaeabering. !his is a sad commentary on the attitude of the bulk ot our citizenry towards the importance ot forest resources in the na tional economy.
