In Chapter 17 of Rilla of Ingleside:

RILLA read her first love letter in her Rainbow Valley fir-shadowed nook, and a girl’s first love letter, whatever blasé, older people may think of it, is an event of tremendous importance in the teens. After Kenneth’s regiment had left Kingsport there came a fortnight of dully-aching anxiety and when the congregation sang in Church on Sunday evenings,

“Oh, hear us when we cry to Thee
For those in peril on the sea,”

Rilla’s voice always failed her; for with the words came a horribly vivid mind picture of a submarined ship sinking beneath pitiless waves amid the struggles and cries of drowning men.

The Navy Hymn
William Whitling, John B. Dykes

Eternal Father, strong to save,
Whose arm hath bound the restless wave,
Who biddest the mighty ocean deep
Its own appointed limits keep;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

O Christ! Whose voice the waters heard
And hushed their raging at Thy Word,
Who walked on the foaming deep,
And calm amidst its rage didst sleep;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

Most Holy Spirit! Who didst brood
Upon the chaos dark and rude,
And bid its angry tumult cease,
And give, for wild confusion, peace;
Oh, hear us when we cry to Thee,
For those in peril on the sea!

O Trinity of love and power!
Our family shield in danger’s hour;
From rock and tempest, fire and foe,
Protect us wheresoever we go;
Thus evermore shall rise to Thee
Glad hymns of praise from land and sea.
