^ KEITH’S SUPER-MASTODON 
1. A Cash Crop for Quick Money—Bears 60 to 90 days after planting. 
2. Holds World’s Record—$216 per Acre per Day on September 14th. 
3. A great Commercial Success—Bears Two Crops instead of one per year. 
4. Our Prices are greatly reduced this year. 
1. —Revolutionizes the Strawberry Business 
With Keith’s Super-Mastodon plants it is possible for you to have ripe 
strawberries to sell on the market, not only in the spring, but also all 
summer and fall—beginning 60 to 90 days after you set the plants. Why 
be content with the one-crop varieties when you can grow Mastodon and 
have berries to sell all summer and fall and in the spring, too, all from 
one planting? And the summer and fall berries are the ones that bring 
the money. 
2. —$216.00 Per Acre Per Day in Summer 
Keith’s Super-Mastodon is certainly the best money-maker in the straw¬ 
berry line today. We know of no other berry bringing $216.00 per acre 
in one day’s picking. For instance,—during one day’s picking (Sept. 
14th) we harvested at the rate of 36 crates (576 quarts) per acre which 
sold for $216.00. This was just one day’s picking. 
3.—A Real Opportunity for House 
wives 
4.—$956.70 Per Acre 
From Spring Crop 
There are thousands of housewives who are 
looking for an opportunity to make a little extra 
money to buy extra things for themselves or 
their homes. A bed of Keith’s Super-Mastodon 
plants will afford you this opportunity. Only a 
small space needed—across one end of your gar¬ 
den—along the back fence. They are easily 
grown. 
And the big Mastodon berries are easily and 
readily sold to your neighbors, tourists, gro¬ 
ceries or on fruit markets. 
Here is what Keith’s Super-Mas¬ 
todon can do for you as a spring 
berry after fruiting all the pre¬ 
vious summer and fall. It did it 
for us. From two-thirds of an 
acre that fruited heavily all the 
summer and fall before (1926), 
we picked and sold to buyers 
5,300 quarts, bringing us $639.00. 
This yield ran above yields of 
any of the common spring varie¬ 
ties fruited in this great berry 
section that season. This goes 
to show that Mastodon is a good 
profitable spring variety, en¬ 
abling you to get two crops of 
fine berries in the same time you 
have been getting but one with 
common strawberries. A Sum¬ 
mer and Fall crop, and another 
(second crop) in the Spring. 
5.—Put Your Extra Lot 
or Garden Spot to 
Work 
6.—$100.00 From Small Bed 
Mr. Burlew and family, shown in the above pic¬ 
ture, purchased 1,000 of our Super-Mastodon 
plants and during the first summer and fall sold 
over 400 quarts of berries at 25 cents per quart 
($100). The next spring he sold 569 quarts of 
berries ($113.80). The summer crop brought 
him at the rate of $1,100.00 per acre and the 
spring crop $1,251.80. Mr. Burlew writes us: 
,f My Mastodon patch has been the attraction and won¬ 
der of the surrounding country. You know what the 1,000 
plants did for me last summer (sold $100 worth). This 
spring we marketed $113.80. They are the only kind to 
have for profit. They have proved a wonder.”—J. M. 
Burlew. 
8.—300 Supply Family of Eight 
Mr. Kurtz at Smithville, O., writes us: “Set 
Mastodon in May, picked first berries in August. 
The 300 plants supplied our family of eight. 
Had our last berries November 6th.’’ 
That extra lot that always grows 
up to weeds—that waste space in 
your garden—that extra space at 
one end of your home lot will 
bring you extra money when set 
to Keith’s Super - Mastodon 
plants. Others make extra money, 
so can you and you don’t have to 
wait a whole year either. They 
begin to bear 60 to 90 days after 
you set them out. 
7.—$60 from Small Bed 
Mr. Parrish of Mt. Clemens, 
Mich., set a small bed, 33x55 to 
Keith’s Super-Mastodon and har¬ 
vested over $60 in berries the first 
Summer and Fall.
