may be expected. In the fall the roots may be dug and stored in the 
cellar, or left in the ground until wanted for use. When stored 
in the cellar they should be covered with soil or sand to prevent 
shriveling. It is thought by some that freezing improves the quality 
of the root. Rust frequently attacks the leaves of this plant, but is 
not usually serious enough to make an appreciable difference in 
the size of the roots. 
Squash .—The squash is somewhat uncertain from a stand¬ 
point of production. Some years this vegetable produces so heavily 
as to be exceedingly profitable, even though the price is not high. 
Other years the yield is scant. This seems to be more a matter of 
the season, than from any organic difficulty. The culture of the 
squash is simple. A warm dry soil is most favorable to its de¬ 
velopment. Some particularly good specimens of Warted Hubbard, 
have been grown in Northern Colorado districts. The smaller 
varieties as Burpee’s Ford Hook, are better adapted to the higher 
altitude and short seasons. One of the worst enemies of the squash 
is the so-called squash bug. This insect is hard to destroy as it 
cannot be poisoned. The best remedy, where only a few plants are 
grown, as in the garden, is to lay pieces of boards on the ground 
near the plants. The insects will collect under these boards during 
the night, and may be killed early in the morning. 
Tomato .—Tomato growing in Colorado is becoming one of 
the agricultural industries. This crop has been grown in the Ar¬ 
kansas Valley for quite a number of years, but in the past few 
years, tomatoes have been grown in the Northern Colorado dis¬ 
trict from Denver to Greeley for canning purposes. Until recently, 
nearly all the canned tomatoes of commerce were put up in the 
eastern states, as Michigan, Delaware, and New Jersey. There the 
seasons are somewhat more favorable for securing larger yields 
than in Colorado. However, the yield here is oftentimes equally as 
good as in the eastern states, and the quality is superior. The 
tomato thrives in a warm, sandy soil. For that reason this plant 
demands frequent shallow cultivation. Tomato growing in a com¬ 
mercial way is confined to the lower altitudes in the State. For 
home use this vegetable may be grown at an altitude of 7,000 to 
8,000 feet. In the high altitudes, particular care should be taken 
to have the plants as large as possible when the ground is ready 
for setting in the open field. In the Experiment Station gardens, 
tomatoes were set this year on several different dates. The first 
setting, made May 10th, was injured by the freeze of May 16th to 
such an extent that it was necessary to reset plants although the 
plants first set were well hardened. The second setting was made 
May 25th. June 4th, two rows of Earlina plants were set that 
had been grown in six inch pots in the green house. These toma-
