"September in The Qu'Appelle Valley" by Ernest Luthi is a warm and vibrant portrayal of the lush landscape during early autumn. The painting features a panoramic view of the Qu'Appelle Valley, a region known for its picturesque hills and rich history in Saskatchewan, Canada.

Dominating the foreground are robust trees in the midst of their seasonal change, with leaves painted in varying shades of yellow, gold, and green. These trees are full, their canopies heavy with the dense foliage of late summer, just turning towards the fiery hues of fall. The thick, textured brushstrokes give the foliage a lively, almost tactile quality.

In the middle distance, a classic prairie church, white and pristine, stands out amidst the verdant green fields, serving as a focal point that draws the eye. Its presence evokes a sense of community and timeless tranquility within the vastness of the valley. The church's simple architecture and the steeple pointing skyward are iconic of the rural landscape.

Beyond the church, the rolling hills of the valley stretch into the distance, their contours highlighted by the golden light of September. The hills are rendered in soft browns and greens, suggesting the undulating terrain and the textured tapestry of the land.

The sky above is a clear expanse with gentle strokes of blue and wispy clouds, indicating a peaceful, clear day. The overall effect of the composition is one of harmony and natural beauty, capturing the essence of the Qu'Appelle Valley in a moment of seasonal transition. Luthi's work here is evocative of the calm and splendor of the Canadian prairies, inviting viewers to appreciate the serene and pastoral elegance of the landscape.
