ing crop-season in which members (or others interested) 
can keep an eye open for superior specimens. 
The award for the largest tree will be made on the basis 
yi Eeeerseme The conditions to be observed are as 
ollows: 
Photographs must be on glossy paper, not smaller than 4x5 or 
3% x5 inches, and must be of sufficient excellence to allow reproduc- 
tion in the “Journal of Heredity” or elsewhere. Photographs in which 
the tree is so small that its details cannot be made out, cannot be con- 
sidered. The measurement of the tree must be given in detail. In 
making it, the only method which may be followed is to take the cir- 
cumference of the trunk at two feet from the ground. It is desirable 
that the full height of the tree and spread of branches, as well as the 
girth, should be stated; if they cannot be measured exactly, they should 
be estimated. Photographs should, when possible, contain some object, 
such as a human figure, which will aid in giving a realization of the 
size of the tree; but such figure should be beside, not in front of the 
tree. It is necessary that the photograph should include the whole tree. 
If there are other trees growing beside it and cutting off part of it, these 
other trees should be included in the picture. Contestants may send 
photographs of as many different trees as they like. 
With each photograph, a statement should be submitted telling all 
that is known about the tree, with reference to its age, the size of 
it bears, the quality of the fruit; the character of the soil and surround- 
ing vegetation. It is particularly necessary that photographers should 
state whether there are many other papaw trees in the neighborhood— 
within a radius, say, of five miles. If the tree is on private land, and 
likely to be destroyed, the fact should be mentioned. It will be helpful 
if photographers can tell to what extent the tree is subject to attacks 
by disease or insects. In short, the council desires to gain as much 
information as possible about the papaw trees of the United States; but 
it imposes as few hard-and-fast restrictions as possible, because of the 
varying conditions under which photographs may have to be taken, or 
under which they have been taken at some time in the past. 
The tree should be shown with full summer foliage. 
All photographs submitted will become the pro: of the American 
Genetic Association, to be kept as a scientific sam oid used in any way 
that the council may think desirable. 
In the award for excellence of fruit, it will not be neces- 
sary to submit a photograph of the tree, since many of the 
igi pe grow in dense thickets where it would be im- 
possible to make a picture. It will be necessary, however, 
to give a description of the tree from which the fruit is 
en, telling approximately how large it is, exactly where 
located, and whether or not it can be transplanted, or twi 
obtained for grafting. The amount of fruit it bears sho 
also be stated. The contestant must send by parcel post to 
the office of the American Genetic Association, 511 Eleventh
