In commemoration of their Centennial Year, Harris Seeds (Joseph Harris Co., Moreton Farm, Rochester, N.Y. 14624) has come up with some new introductions of considerable interest. The catalogue will be sent free upon request.

Quicksilver sweet corn makes it possible to grow white corn with a tenderness and flavor that rival the great Silver Queen, but is ready nearly three weeks earlier. Rugged and vigorous, it is adapted for earl planting and produces excellent fields of well-filled, delicious-looking ears.

Sweet Sal Bircolor sweet corn with mixed white and yellow kernels has a texture and sweetness few others can match. It has the seedling vigor to come up in cold soil and is ready in midseason with tight-packed kernels, straight rows and well filled tips.

Eddp Red lettuce resembles the ole-time favorite, Prizehead, but the glossy green, red-tipped leaves have a deeper, more intense color. A losse-leaf type, it forms clusters of frilled, curly leaves, crisp and tender. Like almost all other kinds, it does best in the cool weather of spring and fall, and poorly in midsummer heat.

Star Trek kgrandiflora petunias, mixed colors of red, rose, crimson, blue and purple, all striped with white, blooms all season long for a fine display in mass plantings and Red Champion Improved hybrid geranium, from seed, grows vigorously and blooms early and over the entire season.

One hundred years ago, Joseph Harris, a farmer from England witt wide agricultural knowledge and experience published his first seed catalogue. The office was right in the home and his children helped package the seeds and send them out. He died in 1892 and was succeeded by his 25-year old son, Selah.

His grandson Joseph became president of the company in 1949. The grandson received the American Seed Trade Association's 1976 award for outstanding service to the seed industry, was president of All-America Selections in 1950-51 and in 1978 received their silver medallion, the highest award for services to horticulture.

Plant breeding is among his chief interests. Now more than 30 vegetable and flower plant breeders, plant pathologists and research technicians on the Harris Seeds staff work to develop new varieties and improve existing ones.
