My Coating is the Best 
Protection for Concrete 
@ I want you to know Bay State 
Brick and Cement Coating is be- 
ing specified by the leading archi- 
tects and contractors not only as a 
coating on cement, stucco, and brick 
surfaces to protect them against 
moisture, but on high grade interior 
work on both wood and plaster. 
@ When you need a coating for 
cement and want something that 
will stand up and give you protec- 
tion and durability, also a pleas- 
ing finish, use the Bay State Brick 
and Cement Coating, which is the 
result of research and experimental 
work for more than a decade. 
Wherever it is used on stucco, con- 
crete, wood, or plaster, it stands up 
better than any other. 
@ You know how necessary it is to 
protect concrete surfaces against 
dampness. My coating is damp 
proof and gives a pleasing ap- 
pearance without destroying the 
texture of concrete and in addition 
is a fire retarder.

SANITATION OF SWIMMING POOLS 
HE work of protecting and purifying 
public water supplies has suggested 
the investigation of the condition of a re- 
lated -subject—the water of swimming 
pools, which forms the subject of a paper 
recently read before the American Society 
of Municipal Improvement by Mr. Mel- 
vin C. Whipple and Mr. John W. M. Bun- 
‘ker, the abstract of which, here following, 
appeared in the Municipal Journal. 
Within a few years the possibility has 
been realized of such pools becoming a 
means for the transmission of disease. It 
is believed that nose and throat affections 
may be, and often are, transmitted by the 
water of the swimming pool. The danger 
of the transmission of intestinal diseases 
is less only because such diseases are more 
rigorously controlled and isolated. At least 
one record is at hand of an epidemic of 
typhoid fever which was spread by a swim- 
ming pool. 
Conclusive data are at hand to show that, 
in spite of the utmost care in enforcing 
sanitary and hygienic regulations upon users 
of a pool, each person adds his quota of 
bacterial contamination to the water. As 
the organic matter which enters the water 
is kept at a relatively high temperature, it 
offers a good culture medium. It has been 
found that a temperature of 75 deg. Fahr. 
greatly favors bacterial growth under these 
conditions over that of 70 deg. 
Consecutive chemical analyses made at 
various colleges in the United States have 
shown that the organic contamination in- 
creases progressively from day to day while 
a pool is in use. Bacteriological analyses 
show a progressive increase up to the point 
where the Malthusian Law asserts itself to 
bring about a balance. 
Experiments have shown that disinfec- 
tion will take care of the bacterial contami- 
nation of swimming pools. Ordinary 
bleaching powder, or calcium hypochlorite, 
now so widely used in water supplies, has 
been selected by all as the most efficient 
substance for this purpose. 
Results achieved point to the efficiency 
of chloride of lime as a disinfectant, when 
applied in quantities that will furnish from 
0.4 to 1.0 part per million of available chlor- 
ine at intervals of one to three days. 
This conclusion has been made more cer- 
tain in the light of confirmatory evidence 
from various institutions, where accurate 
and careful observations have been made of 
conditions governing the use of pools. 
THE OLDEST LIGHTHOUSE EXTANT 
T La Corufia in Northern Spain may 
be seen a fire tower which is, with the 
exception, of the ruins of the Roman 
lighthouse at Dover, the oldest of all ex- 
isting structures of this kind. The exact 
date of the erection of this tower is un- 
known. According to an ancient tradition 
it is accredited to Hercules, whence its name 
Torre de Hercules. Others say that Phoe- 
nicians who had established several colonies 
in Spain, had erected this light-tower for 
their northland cruises. It is more probable 
that the Roman Emperor Trojan (98 to 117 
A. D.) erected this structure. Its inscrip- 
tion also mentions the name of Servius 
Supus of Lusitania as the architect. The 
tower is built of ashlars and is 9 meters 
by 40 meters. It has six separate stories, 
which can only be reached by a circular 
staircase around the exterior of the tower. 
The lighthouse was restored in 1684, but 
at the end of the Eighteenth Century was 
again in ruins. In 1797 it was rebuilt by 
the Spanish government, and still sends | . 
forth its beams.

The Companionship of 
Farr’s Hardy Plants 
There’s a delightful ‘companionship ’’ about a 
group of well-chosen hardy plants that you cannot 
realize unless you own them. Years ago, my hardy 
garden was only a part of my side-lawn. Now it 
has expanded into acres and acres of the choicest 
varieties, and this spring I am watching more eagerly 
than ever for the first sign that another glorious flower- 
pageant is about to be ushered in. 
a few plants, and, if properly chosen, 
these will afford you endless pleas- 
ure and satisfaction. I should be 
more than pleased to be allowed 
to help you plan a garden. i
