Horticulture at High Altitudes 7 
fruits. If they are well mulched with straw in the fall, the mulch 
will aid not only in preventing the plants from bearing but will 
also retard the blooming season in the spring, thus helping to 
avoid damage by late frosts. 
From the small amount of data at hand no definite recommen- 
dations can be made. The writer, however, would suggest the 
Senator Dunlap as a variety for planting until further informa- 
tion is available. 
The everbearing strawberries seem to do well at high altitudes, 
and if it is desired to grow these, the Progressive and Superb 
are perhaps the best varieties. Spring planting is recommended, 
but fall planting (done the latter part of August) may succeed. 
Raspberries . — Fifty plants each of the following varieties of 
raspberries were planted in 1916: Cuthbert, Loudon, Herbert, 
Marlboro, King, Miller’s Red, Turner and St. Regis. A very small 
crop matured in 1917, but the 1918 and 1919 crops were killed by 
late frosts. A better knowledge of local conditions, however, 
would have made it possible to have avoided the injury in 1918. 
Due to the fact that no crop of any consequence has so far 
been produced, definite recommendations can not be made at this 
time. Of the varieties planted, Cuthbert, Marlboro, and Loudon 
are Avell known and successfully grown in many parts of the 
State. St. Regis is one of the so-called ‘Tver bearing” raspberries 
and appears to have some promise. It has a habit of bearing a 
crop in the summer and another in the fall. Herbert is a strong 
growing variety and produces large sized berries of good quality. 
It appears worthy of trial, especially for home use. 
With raspberries, late spring frosts are also a considerable 
drawback. Damage from this cause, however, may be minimized 
by proper handling of the plants at time of uncovering. It is often 
difficult to know just the proper time to uncover the plants in 
the spring; therefore the following suggestions along this line 
taken from Bulletin 206, Colorado Agricultural Experiment Sta- 
tion, (Spur Blight of the Red Raspberry Caused by Sphaerella 
rubina, by Dr. W. G. Sackett) may be of interest here : 
“Just when to take the berries up in the spring is always a 
problem, not because we do not know what practice is best to follow 
but because we do not know what weather conditions to expect. 
On the one hand, if the spring is going to be late, cold and dry, 
little harm will result if the canes are left buried until after the 
first of May; on the other hand, if it is warm and wet, nothing 
could be more disastrous than to allow them to remain covered 
until this late date. The danger from uncovering and taking them 
up too early results from subsequent late freezes during the first 
part of May. The fruit spurs are usually well advanced by this
