Alarmists sometimes write and talk about a shortage in production that 
the world will some day have to face. That day, if it ever comes, is far, far 
away. Put the population of Minnesota at 2,000,000. Till enough land as this 
garden was tilled to supply this population with vegetables, omitting celery 
and potatoes, and perhaps cabbage, and it would require but 17,544 acres of 
land. Put the acreage of Minnesota at 53,000,000. Devote one-half of this 
area to the production of garden products, and till it as this garden was 
tilled, and it will supply with twenty-five or twenty-six kinds of vegetables 
the year around, 3,021,000,000 of people, or about one-fifth the number now 
living on this entire glebe. 
BEST VARIETIES OF TREES FOR STREET PLANTING. 
WYMAN ELLIOT, MINNEAPOLIS. 
The subject assigned to me is one that should receive thoughtful at- 
tention by every person that is a lover of city, town, village or roadside 
adornment. There are many varieties and sub-varieties of our native trees 
that are specially useful for street and ornamental planting. We will confine 
our attention to a few of the most common varieties, in the order in which 
they are most popular with tree and landscape planters. 
First and foremost is the elm (Ulmus americana). No tree can sur- 
pass this for its beautiful proportions. In old trees, especially, from the 
wide spreading buttress-like roots to the wide spreading branches, the 
curvature is beautiful and graceful in the extreme. Soil conditions seem, 
however, to give variety to the outline. It is a rampant grower in moist 
soils, and has a remarkable power of adaptability in all kinds of locations 
and exposures. The rapidity of its growth adapts it to artificial planting 
where shade is soon wanted. It is a great favorite with all shade tree 
planters and when properly and often transplanted while young, it is a tree 
very sure to live when properly planted. There are two other varieties of 
the elm native of our state that are often used for street planting, the slip- 
pery, or red, elm (Ulmus fulva) and the corky white elm (Ulmus racemosa). 
These trees do not grow as large as the white elm, but more compact in 
growth of top. Their wood is much tougher and firmer grained, valuable 
for many purposes where strength is desired. They make fine specimens 
for park and lawn planting. 
There are three other varities of the elm family that are valuable for 
planting in large grounds to give added effect by variety of tinting of foliage 
and symmetry of form. 
First. The Wahoo, or winged, elm (Ulmus alata) is of southern origin 
and a small growing tree that has not been very much used for planting in 
the northern states. If found hardy it would be a valuable acquisition. 
Second. The English elm (Ulmus campestris), as its name indicates, 
is of foreign origin. This is a fine growing tree somewhat different in form 
of growth and foliage from-our American white elm, and a valuable tree 
where variety is desired. The Wynch elm (Ulmus montana) resembles the 
slippery elm in its manner of growth and is a very popular tree wherever it 
has become known, especially in Europe. 
The hackberry (Celtis accidentalis) strictly speaking is not an elm, but 
somewhat resembling the corky white elm in manner of growth, but of 
lighter foliage, which comes into leaf later than the elms. It has a compact,
