OUR SPECIAL SELECTIONS OF GREAT LAKES 
In making these selections, each of them originating from a 
single head, we had in mind to fix regular times of maturity, 
greater uniformity, and insure a high percentage of perfect heads. 
These selections are based on sure-heading quality, vigor, slow 
bolting, resistance to tip-burn, high temperatures and slime; and 
fixing a small or flat midrib to present a perfect base when cut. 
They are as follows: 
Great Lakes No. 428, Early Strain (w.s.). Gray-green in color, the 
wrapper leaves lay back from the head, which is well rounded and 
has a smooth base and small ribs. Very uniform in maturing, it is 
at its best when fully mature. Records show 95% ready for mar- 
ket at first cutting. 75-80 
Great Lakes No. 407 Medium Strain (w.s.). Specially selected for its 
resistance to tip-burn, sun-burn and rain. Bright green color, large 
outer leaves stand erect and protect the heads from the elements. 
Very slow to bolt, stands up under most adverse weather conditions 
and has succeeded well in all sections of the country where it has 
been tested. 90-100 
Great Lakes No. 659 Late Strain (w.s.). Plant is dark green, resistant 
to tip-burn and sun-burn. Head is large, round and very firm and 
of excellent quality. The head is completely covered by the upright 
extra fringed leaves so that sun-burn is impossible. An outstand- 
ing strain for late market. It is a sure-header and is particularly 
adapted for those sections where it is difficult to grow head lettuce 
because of weather conditions. 110-120
