Do you know a place where the wild rice grows? Ah, so did the Passenger Pigeons, once upon a time!

But if you know none of these places, even then you can stand near where the flocks used to fly when they were on their journeys. All of you who live between the Atlantic Ocean and the Great Plains can go to the door or a window of the house you live in and point to the sky and think: "Once so many Passenger Pigeons flew by that the sound of their wings was like the sound of thunder, and they went through the air faster than a train on a track, and the numbers in their flocks were so many that they hid the sun like great thick clouds."

When you do that, some of you will doubtless see birds flying over; but we fear that not even one of you will see even one Passenger Pigeon in its flight.

What happened to the countless millions is recorded in so many books that it need not be written again in this one. This story will tell you just one more thing about these strange and wonderful birds, and that is that no child who reads this story is in any way to blame because the dove is lost. What boy or girl is not glad to think, when some wrong has been done or some mistake has been made, "It's not my fault"?

Once, so many flew by, that the sound of their wings was like the sound of thunder.

Even though this bird is gone forever and forever and forever, there are many other kinds living among us. If old Mother Earth has been robbed of some of her children, she still has many more—many wonderful and beautiful living things. And that she may keep them safe, she needs your help; for boys and girls are her children, too, and the power lies in your strong hands and your courageous hearts and your wise brains to help save some of the most wonderful and fairest of other living things. And what one among you all, I wonder, will not be glad to think that you help keep the world beautiful, when you leave the water-lilies floating on the pond; that it is the same as if you sow the seeds in wild gardens, when you leave the cardinal flowers glowing on the banks and the fringed gentians lending their blue to the marshes. For the life of the world, whether it flies through the air or grows in the ground, is greatly in your care; and though you may never win a prize of money for finding the dove that other people lost, there is a reward of joy ready for anyone who can look at our good old Mother Earth and say, "It will not be my fault if, as the years go by, you lose your birds and flowers."

And it would be, don't you think, one of the greatest of adventures to seek and find and help keep safe such of these as are in danger, that they may not, like the dove, be lost?
