Spring brings soft ground, and horse’s hoofs are heavy. You 
either wait, and the grass gets too long, or you put such holes in 
the ground as a season’s rolling can hardly level.

of iron sulphate to a gallon of water seems to give 
the best results. The solution must be applied 
at least three times, at intervals of about two 
weeks. In Colorado the most effective results 
were obtained in late summer. It is important 
that the spray be applied in the form of a fine 
mist driven forcibly into the crowns of the plants. 
Cloudy, damp weather is particularly favorable 
if the application is not followed by rain within 
twenty-four hours.

Specialties for Early Spring Planting— | 
' Year after year the garden increases in charm and value as the shrubs and 
plants increase in size and blooming power. Early spring is a desirable time 
for setting most plants, and in my collection at Wyomissing may be found 
specimens that are suitable for every phase of gardening. A few are here 
noted — to list all would be impossible: 
Japanese and Asiatic Shrubs — Berberis, Flowering Cherries, Enkian- 
thus, Cotoneasters, Corylojrsis and others. 
French Lilacs, Philadelphus and Deutzias — a complete collection of 
Lemoine’s new creations. 
Rare Specimen Evergreens for the formal garden, lawn groups and rock 
gardens. 
I iardy Asters, Phloxes Delphiniums, Chrysanthemums and other peren- 
nials for spring. 
An Emergency Edition of Farr's Hardy Plant Specialties (issued because 
of the great demand for the sixth edition) will be sent to those who request 
a copy.

This material is damaging to most metals, 
therefore it should be used in a spray pump hav- 
ing brass fittings, and never put into any iron, 
galvanized iron, or tin vessels. Moreover, all 
utensils must be thoroughly rinsed with water 
after the work has been completed, and the mov- 
able parts of the pump kept well oiled. It is 
likely to cause a rusty stain if it touches walks and 
curbings, so should be used carefully, or some sort j 
of protecting material laid down. The weak 
solution does no serious injury to the grass, j 
although it may seem to affect it at first That 
part of the lawn sprayed however will eventually | 
take on a greener hue than before — but it is 
deemed advisable to pay particular attention to J 
watering and mowing the lawn, in order to en- | 
courage the growth of the grass. And White j 
Clover, if present, will probably be killed out. 
HOW TO MAKE A “CROSS” 
T HE essential point in crossing is to prevent 
the stigma of the chosen seed-parent from 
being pollinated by any flower except the one 
desired as a pollen parent. In order to accom- 
plish this: (i) remove all flowers that have opened 
and shed any pollen; (2) select several buds that 
look as if they would open in a day or two, and 
gently pulling their segments apart hold the bud 
open with the fingers of the left hand while the 
immature anthers are removed by the fingers or 
by means of tweezers. Be sure that you take 
out all (six in Lilium). 
Cover the bud with a paper bag, leaving it 
for two or three days. Then remove it and ex- 
amine the stigma, the knob-like end of the pistil. 
If it be viscid and glistening in the sun, it is ready 
for the pollen of the chosen species. Cover it 
well with pollen and replace the bag, keeping it 
on until the stigma withers and further danger 
of foreign pollination is past. 
The paper bag has certain disadvantages. 
Damage to some of the flowers in removing or 
replacing the bags, is certain; and on a warm day, 
the atmosphere inside the bag will become hot 
and steamy and may prevent seed formation. 
On a large scale omit the bags entirely, but take 
extreme pains to keep all the buds on the patch 
emasculated. This method is practically as ex- 
act as the former method if the different species 
are planted in isolated groups in different parts 
of the garden. Its great drawback lies in the 
necessity for the rigid surveillance of every bud. 
Give each cross some distinguishing mark, or 
write the names of the parents on a label and 
fasten it to the flower stalk. — H. E. Gilkey. 
[Though the method of procedure here out- 
lined refers specifically to work on Lilium, still 
the same principles apply in general to all ordinary 
flowering plants. The smaller the parts or the 
more intricate the work the more difficult is the 
handling, necessitating practise and patience.]
