legumes and summer till for potatoes. Pea and oat hay is good hay to 
produce milk, and if planted early on rightly managed land is a sure 
crop. Mexican beans are a paying dryland crop. The great interest in 
good alfalfa seed is sure to result in profitable growing by drylanders of 
special varieties of alfalfa for seed purposes. And rotation with peas or 
beans and with alfalfa when it has to be plowed up will increase all the 
farm crops on the plains. See Julesburg 1910, herein. 
Plowing for potatoes will be done the summer before; or, after sum¬ 
mer tilling, will be done in the fall. Spring plowing is a gamble. Fall and 
spring tilling will be universal. 
Summer tilling will promote 
good shape in the potatoes 
grown the next year. 
Planting is well done deep 
on the dryland and is one of 
the things upon which good 
shape, early set, and good seed 
depend. It is not advisable 
to plant with a plow. Use a 
horse planter or plant as deep 
as possible with a hand 
planter. 
Cultivate Shallow’ following 
cross harrowings. Do not cul¬ 
tivate when it is not needed, 
but keep out all the weeds and 
break every crust. 
Machine Diggers of the four 
horse elevating type are often 
too expensive for dry land 
neighborhoods while plows are 
too wasteful of potatoes. The 
double beam rod shaker digger 
shown in the cut is a good 
compromise, as it is cheap and 
works well on small or mature 
vines when the ground is loose 
and not wet.

and diseases which in 1910 hurt the earlier sorts, even including Pearls, 
left our Rurals by far the heaviest yielding class. The yield of the Dew- 
drops (Stake 150) maturing with Pearls we discard because of the un¬ 
desirable shape of the tubers. The net weight of the Cobblers and the 
gross weight of the Ohios were about the same, and both were here of 
fine table quality, and w’ere ready the first of September. All varieties 
were dug September 21, and at this date Rurals though thin skinned were 
mealy and wdiite fleshed.
