BY ELBRIDGE S. BROOKS.

igh on a Saxon hill-side overlooking the pleasant valley of the Itz, and in the shadow of the loftier Frankenwalds, stands an old castle now gray with age and rich in memories. In one of its many guest rooms, near an open window, about which crows and jackdaws hung with swirl and clamor, there sat, many years ago, a stockily-built, firm-featured, fearless-eyed man writing a letter.

Armed men fill the castle; upon its walls and on its highest turrets watchmen stand on guard; above it floats the standard of the Elector of Saxony; and the great gate opens only to the summons of those who come with credentials or password.

The time is one of anxiety and excitement, for the Protestant Princes of northern Germany have taken a bold stand against their lord the Emperor. Messengers ride daily to and from the castle, and letters are sent now this way and now that, freighted with important measures or hot with words of protest, counsel, and appeal, strengthening those who waver, restraining those who are over-bold.

As by his open window in the ancient castle of Coburg, where his presence is honored and his word is law, the strongman sits at work. What is the letter that he writes? Who is the Prince or preacher for whom his words of wisdom are penned? Is he a soldier issuing commands, or a councillor sending advice to Elector, Duke, or King?

We draw near the writer, and as we look over his shoulder, following the queer old German script his quick quill traces on the paper, this is what we read:

"Grace and peace in Christ. My dear little son, I am glad to hear that thou learnest well and prayest diligently. Do this, my son, and continue it; when I return home I will bring thee a fine fairing.

"I know a beautiful cheerful garden, in which many children walk about. They have golden coats on, and gather beautiful apples under the trees, and pears and cherries and plums; they sing, and jump about, and are merry; they have also fine little horses with golden bridles and silver saddles. And I asked the man, 'Whose children are they?' He replied, 'These are the children who like to pray and learn and are pious.' Then I said, 'My good man, I have a son; his name is John Luther, may he not also come to this garden to eat such nice apples and pears, and ride such fine little horses and play with these children?' And the man said, 'If he likes to pray and learn and is pious, he shall come to this garden with Philip and James; and when they all come together they shall have pipes and cymbals, lutes and other musical instruments, and dance, and shoot with little cross-bows.'

"And he showed me a fine meadow in the garden prepared for dancing, there being nothing but golden pipes, cymbals, and beautiful silver cross-bows. But it was yet early and the children had not dined. Therefore I could not wait for the dancing, and said to the man, 'My good master, I will go quickly and write all this to my dear little son John, that he may pray diligently, learn well, and be pious, that he also may be admitted into this garden; but he hath an Aunt Lena whom he must bring with him.' The man answered, 'So be it; go and write this to him.'
