Why are we concerned with boxes whose lids don’t close properly?
This is not just curators and conservators being pernickety; we really do have very good reasons to make sure that every closed box stays shut.
Museum collections contain a lot of valuable things that are easily perishable. Swords are made to be tough, but - believe it or not - even swords are not indestructible.
Iron rusts when it gets wet. Iron also rusts because of moisture in the atmosphere. Other metals can corrode in much the same way. If we are not careful we would end up with merely a bag of rust!
Therefore, we store all manner of sensitive objects (including cannonballs!) in what we call “micro-environments”. While many of our stores and galleries are air-conditioned, the humidity in the air is often too high to prevent these delicate objects from rusting.
Micro-environments are boxes or plastic pouches that contain one or several objects, plus a chemical that regulates the humidity within the box or pouch. This chemical is silica gel – if you have ever bought an electrical item the packaging probably contained a little sachet saying “Do not eat!”. The little granules in this sachet are silica gel. It is very widely used to keep things dry. Including in museums.
Once we have packaged our objects with silica gel we do not want moisture from the atmosphere to get into the box; that’s why we make sure the box closes properly. Only then will the objects be safe and dry, and ready for display or study.

Our expedition has now drawn to a successful close. Our collections of several thousand specimens have (mostly) been successfully exported from Ecuador and initial analysis of them has started. Entomological expeditions to remote areas are great fun of course. However the less glamorous but harder work comes later, involving months or years of detailed study during which new species are described, evolutionary trees constructed, and ecological or biogeographic conclusions etc. are developed.
In the field there may be great excitement about finding a particular insect but to a scientist, the level of excitement can only grow as the real significance of the finding is revealed subsequently through painstaking study and reference to our already extensive collections. Already we have glimpses of results that might tell us more about how the insect fauna of the upper Amazon Basin came about. For example the unexpected presence of Cladodromia (a classic ‘Gondwanan’ genus) suggests there has been immigration from Patagonia whereas the high diversity of Neoplasta (which is essentially North American) hints at a south-bound migration along the Andes. On the other hand, an almost complete absence of Hemerodromia puzzles us as it is widespread in the lower Amazon so why didn’t we find it higher up? We suspect that the answer may be that it has only recently arrived in South America and is still spreading to Ecuador. Then again the unseasonal rains (due to a strong El Niño this year) may be a factor. Investigations continue.
In the field, our successes were often hard-won; difficult slogging through trying terrain, inclement weather, frustrating officialdom and many other factors sometimes worked against us it seemed, and intermittent access to the internet made writing these blogs challenging at times. We have been very fortunate in that our expedition was entirely and well-funded by the Brazilian Government as a part of their noble and ambitious efforts to understand the biodiversity of the Amazon. Our own exertions will plug one significant hole in knowledge and contribute to greater appreciation of Amazon biodiversity.

Back to civilization again - the regional capital of Loja, a small town nestled under forested Andean slopes and home to the regional Ministry of Environment where we must go once again, to obtain permission to move the samples we have collected back to Quito.
Unlike our previous brush with officialdom in Tena (our samples from there still have not been released!... but we have some local support to ensure that they eventually will be), the officials in Loja were helpful, polite and efficient! We had allowed 2 days to process the permissions in Loja, but in the event, we received our permits within 30 minutes, leaving us the best part of 2 days to explore the town and sample the local culture and cuisine.
Meanwhile, here are some more photos from our time in the field.

Again this month, a number of interesting objects have been added to the industry & transport collections. The photograph below was taken on 22nd July 1926, and shows a group of 29 slate quarrymen. The location is unknown, but it was probably taken at either Dinorwig or Penrhyn slate quarry. If you are able to help identify where the photograph was taken, or recognise any of the men we would love to hear from you.
These three ceramic pieces were designed and made by the artist George Thompson, a potter resident in Amlwch, Angelsey. They are inspired by the Parys Mountain copper mines.
Ceramic plaque with red ocre slip and copper glaze.
Ceramic pot with stand made from pink crank clay with graphite and copper glaze.
Ceramic dish with graphite, red ochre and orange ochre slip.
The photograph below shows the remains of a Cornish beam-engine house and chimney stack at Parys copper mine, Anglesey, 1964.
This is a diorama of Parys mountain copper mine from the museum’s collections. It was made about 1967 for display in the industry galleries at Cathays Park.
This medal commemorates the cutting of the first sod of the King’s Dock, Swansea. On the 20th July 1904 the Royal Yacht Victoria & Albert arrived in Swansea Bay. The yacht arrived at the Prince of Wales Dock where King Edward VII and Queen Alexandre disembarked. The dock was named ‘Kings Dock’ in his honour. After the ceremony the King and Queen rode through the streets of Swansea in an open top carriage. The Dock was official opened on the 20th November 1909. It covers 72 acres (29 ha), and is still in use today, being the main dock of the Port of Swansea.
Photograph showing congested shipping (both sail and steam) at King's Dock about 1910. Not long after the dock was opened.
The view below shows the King’s Dock. It was taken by the photographer John Eurof Martin and dates to the mid-20th century.
