There is a very singular shrub which grows abundantly in the west and is to be found in all parts of Texas. The mesquite, sometimes called the "mosquito tree," is a very slim and willowy looking shrub and would seem to be of little use for any industrial purposes; but it has extraordinary roots growing like great timbers underground and possessing such qualities of endurance in all situations that it was once valued as pavement material. It is said that the city of San Antonio was once paved with these roots. The mosquito tree reminds us of those Christians who make little show externally, but their growth is chiefly underground-out of sight in the depth of God. These are the men and women that God uses for the foundations of things, and for the pavements of that city of God which will stand when all earthly things have crumbled into ruin and dissolved into oblivion. Deeper, deeper let the living waters flow; Blessed Holy Spirit! River of Salvation! All Thy fullness let me know.
