On this food I can ride or walk _days at a time_, without anything else.

Grant's crackers, Horlick's Malted Milk tablets, and Ghirardelli's chocolate are the best of their kind, and all are nutritious to the full, as well as delicious to the taste.

For drink I find Horlick's Malted Milk the most comforting and invigorating, and it has none of the after "letting-down" effects that accompany coffee drinking..
