TBEACLE MUSTABD WALLFLOWEE. 37 



" Yellow Rockets were quite out of fashion, and only double 

 purple and white in vogue." 



The Treacle Mustards are handsome plants. The Garlic 

 Treacle Mustard, or Sauce-alone (Erysimum alliaria), woulcf be 

 valued if its strong scent of garlic did not warn off all contact. 

 Its flowers are large and white, and its heart-shaped toothed 

 leaves a bright glossy green. 



The Worm-seed Treacle Mustard (E. cheiranthoides), grows

 of Richmond Castle. The building stands upon a steep rocky 

 hill, with the turbulent Swale flowing at its foot. The old 

 walls are difficult to scale, and the gorgeous orange and umber 

 Wallflowers flourish undisturbed in the crevices. 



" Flower of the solitary place! 

 Grey ruins' golden crown,

I once rashly mentioned my desire for some of these plants to 

 a generous adventurous young midshipman. He said nothing 

 at the moment, but the next morning he brought me both 

 plants and flowers. Often as I have looked at those dangerous 

 old walls I have shuddered to remember the risk he ran. One 

 slip of the foot, and the daring which has since been a safe-
