Guaranteed Fresh and Full Spawned 
As is well known, good spawn is one of the chief foundation 
stones in successful mushroom culture and should receive the 
first attenti m. Much better spawn can be got to-day than four- 
teen years ago when the Watson Brand was first put on the 
market, but this improvement lias been brought about largely 
through the educative influence and the liberal advertising given 
to a superior article. Although spawn closely approaching the 
Watson in quality can be got from one or two sources to-day, 
it is still true that none of them are equal in two important 
respects: (t) yield and (2) earlincss. The Watson has been 
tried again and again alongside the most highly lauded and has proven the heaviest cropper, 
and the earliest to come into bearing. Another reform in which the Watson Brand 
was the pioneer is the cost of spawn. Absurdly high prices were the rule until a more rea 
sonable and equitable figure was forced on the most conservative by the example of a first- 
class brand being sold at a fair price. Notwithstanding the keen competition of to-day the 
Watson Brand figures are as low as any reliable stock can be bought for, while the quality is of 
the same high standard as heretofore. This being granted it follows that mushroom growers 
should procure their spawn from the pioneer in "a good article at a fair price and take no 
chances with importers of less experience.
