GENERAL REMARKS.—During the next month the boilers and hot water 
pipes should be overhauled, and all defects made good before we are likely 
to have any cold spells, as so often happens in the autumn, when these jobs 
are left over. All boilers should be flushed out, and refilled with soft water 
if possible, and all faulty joints should be renewed. It is cheaper in the 
end to renew faulty joints than to patch them up, as they have a weakness 
for bursting in frosty weather, just when they are most wanted to be in 
good working order. Where saddle section boilers are used, all brick 
setting and flues should be overhauled and put in good order, so that no 
faulty flues will be discovered in the winter time. Here we use the sectional 
boilers and find them very easy to work, as the flues and every part of them 
can be easily got at, and it can be seen at once whether the boiler or stoker 
is at fault. We find, too, that sectional boilers are much more economical 
to use, especially where high temperatures are required, for there is 
practically no waste with fuel, as the whole of the boiler is heating surface. 
For long distance driving they are very fine for maintaining temperatures, 
very even with very little labour and attention, and should anything go 
wrong in winter, it can easily be seen if it is the boiler that is leaking, 
without pulling down a lot of brickwork. 
Tue Houses should also be overhauled, and all cracked and broken 
glass renewed. Any rotten rafters should be seen to before the weather 
gets cold. Houses that require painting should be done and made water- 
tight for the winter. 
WaTERING.—Plants should be looked over every day, as practically 
everything is now growing. Ifa plant is dry give it a good soaking, not 
just moisten the top, especially where the houses are lightly shaded. All 
hanging plants should be examined every day, and the dry ones plunged ina 
bucket of water to make sure they get soaked through. It is no use watering 
a plant with a can when it has got very dry, especially if in a basket, as it 
just runs off and does no good. Newly potted plants should be well looked 
after when watering, as many species soon suffer if left too dry. If a plant 
is in good condition it will seldom shrivel when potted, if well looked after 
afterwards. Givethem a good soaking, then let them dry out before giving 
more, as sprinkling the surface every day is very misleading, for the tops are 
continually wet and underneath the compost is quite dry, and the plants 
shrivel in consequence. 
CyYPRIPEDIUMS, PHAL&NopsSIS, and all the soft-growing section should be 
kept well shaded, with plenty of moisture in the houses, giving air every day 
if possible. Keep them well syringed, especially when the outside conditions
